A network element is selected and assigned to a test channel at a first modulation scheme at a predetermined power level to achieve a predetermined PER. The network element transmits a test signal and the network controller measures the signal to noise ratio (SNR) in the received test signal. If the SNR is not within a predetermined tolerance range of an estimated SNR for the modulation scheme at the predetermined PER, the modulation scheme is determined to have excessive phase noise or narrowband interference. Each available modulation scheme is tested by instructing the network element to transmit the test signal using each modulation scheme and assigning the power level of each modulation scheme. The suitable modulation schemes may be determined.

The idle data has an idle data pattern, which can be controlled such that a power spectral density of a signal carried by at least one channel is shifted in order to reduce Raman crosstalk between the channels. For example, the power spectral density may be shifted away from lower frequencies of the channel, and toward the higher frequencies, by controlling the idle data pattern. Alternatively, the power spectral density may be shifted towards unused frequencies of the channel, by controlling the idle data pattern.

A method and apparatus for converting FFE (72) and FBE (76) coefficients from a DOCSIS compatible cable modem termination system upstream equalizer into FFE only coefficients to be sent down to the cable modem which transmitted the training burst which resulted in convergence on the FFE and FBE coefficients. The method involves programming an FBE like conversion structure comprised of an FFE filter and an FBE filter whose outputs are summed (70) with the FFE and FBE coefficients from the CMTS equalizer. The FFE coefficients are stored in the FFE filter of the conversion structure. The FBE coefficients are stored in an FBE filter of the conversion structure. Then, an input vector which simulates the Dirac function (an impulse) is input to the conversion structure to derive coefficients at its output (86) which define the impulse response and transfer function of the conversion structure. These coefficients are the FFE only coefficients which may be used to select a subset of 24 for sending to the cable modem.
A communication device (202) converts a bit stream to multiple symbols and provides encryption at a physical layer by shifting a phase of each symbol of the multiple symbols to produce multiple encrypted symbols. Each encrypted symbol of the multiple encrypted symbols is modulated with an orthogonal (214) subcarrier to produce at least one modulated subcarrier and the at least one modulated subcarrier is then transmitted (278) via a wireless link. On a receive side (260), a receiving (260) communication device (250) receives the transmitted (230), encrypted symbols and provides decryption at a physical layer by shifting a phase of each encrypted symbol in correspondence with the phase (234) used to encrypt the symbol at the transmit side.

METHOD AND APPARATUS FOR ENCRYPTION OF WIRELESS COMMUNICATION
A communication device (202) encrypts symbols at a physical layer in order to improve encryption of data transmitted over a wireless link. A symbol mapper (208) of the communication device receives a bit stream comprising multiple bits and maps the multiple bits to multiple symbols. An amplitude and phase adjuster (210) of the communication device receives the multiple symbols and encrypts the symbols by applying at least one of a phase shift and an amplitude adjustment to each symbol to produce multiple encrypted symbols for transmission over a wireless link. In another embodiment of the present invention, a communication device (250) is provided that is able to decrypt the encrypted symbols by applying at least one of a phase shift and an amplitude adjustment to each encrypted symbol that corresponds to a phase shift or an amplitude adjustment applied to the symbol by a transmitting communication device.

A system and method for efficiently adding a new network resource to a digital video network, without the need to purchase costly ancillary network hardware or extensive manual configuration, is disclosed. The inventive system and method provide for a loop-through for adding new resources to a digital video network. The present invention provides for the resources to be daisy chained from the network switch, where each resource is configured simply as either a loop-through ("LT") resource or the "last" resource in the daisy chain. Then, only upstream traffic with Media Access Control ("MAC") addresses of upstream LT resources are transmitted out of the loop- through by the last network resource.
A communication system (100) determines whether to establish a point-to-point or point-to-multipoint communication for conveyance of Multimedia Broadcast Multicast Services (MBMS) data based on a number of user equipments (102-104) being serviced by the communication system for MBMS service. The system broadcasts an access probability factor (154) in a control message to the user equipments. For a large number of MBMS users being counted (158), the method will select a point-to-multipoint broadcast (160). If the number of user equipments being counted is relatively small, the access probability factor is modified by a ratio of the number of point-to-point connections over the point- to-multipoint connections over the number of users being counted (174). The UE may need to join multiple base stations' in the counting procedure to obtain the system diversity gain.

METHOD AND APPARATUS FOR MANAGING PACKET DATA LOSS IN A WIRELESS NETWORK
Various embodiments are described to address the need for more effective management of packet data loss in wireless communication systems. When a packet data destination (131) that is receiving a flow of packets for a packet data service instance indicates to the packet data source (141) of the flow that the flow should be suspended, it also indicates to the source how to process packets for the service instance while the flow transmission is suspended. For example, the packet data destination may indicate an event or condition that is triggering the flow suspension, the source can then begin buffering packets, discarding packets, starting timers, and/or taking other packet processing actions to manage packet data loss in view of the packet data destination's indication. Alternatively, the packet data destination may explicitly indicate the packet processing actions the source should take while the packet flow is suspended.
A method (30) for controlling flow of a video content signal through a communications system, such as a video on-demand system (10) creates (39) a unique message for each individual video content signal and attaches (41) the unique message to each individual video content signal prior to transmitting (41-47) the video content signal through the communications system (10) to a designed end user system (19). In one exemplary embodiment, the unique message comprises an in-band signaling message, such as a message inserted in a program map table in an MPEG packetized signal.
