Abstract

A fractional up-sampling filter is configured to convert a lower data rate to a higher data rate by using methods of interpolation to generate output digital data that corresponds to the higher data rate. For example, if the higher data rate output is 4/3 of the lower data rate input, then for every three (3) digital data values originally sampled by the fractional up-sampling filter, four (4) output digital data values are generated and output from the filter. These output digital data values are obtained by methods of interpolation. Interpolation is performed using different filter coefficients depending on the relative timing of the output digital data rate versus the original sampling rate. The fractional up-sampling filter utilizes a high frequency master clock to derive the fractional relationship between the original sampling rate to the new fractional sampling rate.

Automating the calibration process reduces the engineering evaluation time and mass production test time. The calibration settings vary as a function of frequency, and the calibration circuit automatically determines the proper calibration for any frequency application. The calibration circuit enhances communication performance by comparing and computing a time difference between a reference path and a feedback path. The calibration circuit is configured as part of a phase modulation path within a modulation circuit. The calibration circuit provides for calibration without prior knowledge of the system and reduced factory test time. The calibration circuit provides numerous advantages, including, but not limited to, accurate system results for time, frequency, temperature, and process variations with each calibration, or tuning.

Abstract

A technique of packet resending control that is effective for a mobile node in a home agent is to be disclosed. An MN (10) selects a packet transferred to a specific care-of-address in an HA (60), a packet with a specific flow information, a packet transmitted from a specific communication partner node (for example, an CN (40)), etc. from capsulated packets transmitted to itself after the HA receives on its behalf, and requests the HA to carry out buffering of selected packets when the selected packets are transferred. For example, even when connection with an MN becomes unstable and a packet from an HA is impossible to arrive at an MN, the HA is possible to resend the packet subjected to the buffering, so that delay of packet arrivals at the MN can be reduced in comparison with the case that the packet is resent from the CN.

Abstract

Provided are a frequency allocation method and a detection method capable of simultaneously obtaining a frequency diversity gain and a time diversity gain. In this method, most of signals transmitted from a plurality of transmission antennas of a transmission device are not overlapped by one another on a frequency region by allocating a frequency for each of the transmission antennas by using one of the following methods: the Distributed-FDMA method for allocating a distributed frequency band, the Localized-FDMA method for allocating a local frequency band, and the Hybrid-FDMA method for allocating a mixed frequency band. Signals transmitted from the transmission antennas are received and the received signals are subjected to a time-space inverse Fourier transform so as to convert the received signal from the frequency region to the time region and perform MIMO detection on the time region, thereby detecting the transmission signals from the transmission antennas.

Abstract

A transmitter apparatus and a method for switching modulation schemes of the transmitter apparatus wherein a stable reduction of interference power can be achieved during switching transmission band limit filters. During switching the modulation schemes, a switching control part (106) switches, in accordance with a modulation scheme, transmission band limit filters (109-111;115-117), and further controls signal switches (125,126) to switch, as transport signals to be inputted to D/A converters (112,118), from outputs of the transmission band limit filters (modulated signals) to outputs of a storing part (124) (DC signals) before switching the filters. The switching control part (106) switches from the DC signals to the modulated signals after switching the filters. The storing part (124) has stored DC values that are the effective values of the modulated signals. During a predetermined interval in the period of switching the modulation schemes, the transport signal is a DC signal, and the transmission spectrum of this interval is non-modulated spectrum having no spread of frequency. Therefore, the interference power caused by switching the filters can be reduced.

Abstract

Disclosed is a stereo audio decoding device and others capable of reducing a stereo audio encoding bit rate and suppressing degradation of audio quality. In this device, a section 0 where only an L-channel signal SL(n) exists is identified, a monaural signal of the section 0 transmitted from the stereo audio encoding side is made to be an L-channel signal of section 0 SL(0)(n), and the L-channel signal SL(0)(n) of the section 0 is scale-adjusted so as to predict an R-channel signal SR(1)(n) of a section 1. A contribution of the R-channel signal SR(1)(n) of the predicted section 1 is subtracted from the monaural signal of the section 1 so as to isolate the L-channel signal SL(1)(n) of the section 1. This device continuously repeats the aforementioned scale adjustment and isolation process so as to obtain the L-channel signal SL(n) and the R-channel signal SR(n) of all the sections.

Abstract

The invention relates to method for providing a multicast service from or via an application server to a mobile terminal within a mobile communication system, wherein the mobile communication system provides a downlink multicast or broadcast service (DMBS) that can be utilized for transmitting the downlink multicast data to the mobile terminal. Further, the invention relates to a mobile terminal and network entities that participate in this method. To enable an efficient provision of a bidirectional multicast service to users, wherein a DMBS may be used for providing downlink multicast data to the users, the invention proposes that the mobile terminal requests an application server to route downlink multicast data through the resources established for the multicast service instead of the resources for the DMBS, upon receiving a notification that a point-to-point connection is to be used for the downlink multicast data transfer. Thereby, the establishment of additional RAN resources for DMBS can be prevented.

Abstract

The invention relates to a method for managing mobility of a mobile node, which is registered to a subset of network access entities (NAE). A location update is necessary because the MN moves from a first network area served by the first router to a second network area served by the second router, keeping the same IP addresses. In response to a trigger from the MN, the second router requests from the first router information on the registered NAEs, before they are informed to route data, destined for the mobile node, to the second router. Furthermore, the global IP addresses of the MN, created based on the prefixes of the registered NAEs, are updated. To expedite the address configuration after handover, the second router generates a IP address configuration message for the MN, comprising address prefixes of only the registered NAEs, without prior reception of a router solicitation message.

Abstract

A simple system is used to achieve both a process in which particular information is reproduced in real time while being detected from an input data and a process in which particular information is detected from an input data at a high rate. For this achievement, a control means (108) switches, based on mode information from a host CPU (105), between a reproducing/detecting means (102) for reproducing, in real time, particular information, such as digital watermarking information included in an input data, while detecting that particular information and a high-rate detecting means (103) for detecting, at a higher rate than a usual reproduction rate, particular information included in an input data. In this way, a single signal processing apparatus (101) can perform both a reproducing/detecting process and a high-rate detecting process.

Abstract

A communication apparatus capable of detecting a device on a different network in a router-multistage network composed of a plurality of routers without requiring the user to have special knowledge or to pay high cost. If a communication apparatus (101) cannot detect a desired device on its own network, it requests a connection support server (001) securing communication paths with all devices on the home network to relay a request for the detection of the device. The connection support server (001) transfers the relay request for the detection of the device to an arbitrary device belonging to a network different from the network to which the communication apparatus (101) belongs. The arbitrary device as a proxy detects the device and transfers information on the detected device to the connection support server (001). The communication apparatus (101) acquires the information from the connection support server (001) to detect the device on the different network.

Abstract

A sound encoder enabling prevention of deterioration of the sound quality of a reproduced signal even if the harmonic structure is broken in a part of the sound signal. The filter state position determining section (111) of the sound encoder judges the noise characteristic of the first-layer decoding spectrum and thereby determines the band of the first-layer decoding spectrum to be used to set the filter state. A filter state setting section (112) sets the first-layer decoding spectrum contained in the determined band out of the first-layer decoding spectrum as the filter state. A filtering section (113) performs filtering of the first-layer decoding spectrum according to the set filter state and the pitch coefficient and computes an estimate spectrum of the input spectrum. An optimal pitch coefficient is determined by a closed loop processing from the filtering section (113) through a search section (114) to a filter information setting section (115).
