A method and apparatus for encoding a signal is provided herein. During operation a wideband signal that is to be encoded enters a filter bank. A highband signal and a lowband signal are output from the filter bank. Each signal is separately encoded. During the production of the highband signal, a downmixing operation is implemented after preprocessing, and prior to decimating. The downmixing operation greatly reduces system complexity. In fact, it will be observed that the highest sample rate in the prior-art implementation is 64 kHz whereas the sample rate in the system described above remains at 32 kHz or below. This represents a significant complexity saving, as do the reduced number of processing blocks.

Spatial noise is reduced in an image having a plurality of pixels by detecting object boundaries and unstructured areas in the image and applying 3-tap high pass filters to each pixel in the image in at least four, but less than eight directions to determine the best direction for local low pass filtering. Low pass filtering is applied only along object boundaries and unstructured areas within the image so as to minimize the tendency to blur image edges. Using only four high pass filters to locate horizontal, vertical and diagonal image edges passing through the center of a 3x3 pixel array provides good results.
An method (500) and apparatus (100) for adaptive echo and noise control. A signal can be received at an input (140) to a communication or electronic device. Background noise in the signal can be determined. The order of noise suppression and echo cancellation can be adaptively determined (110) based on the background noise in the signal. Adaptively determining the order of noise suppression (230) and echo cancellation (220) can be performed by comparing the background noise to at least one threshold, performing echo cancellation prior to noise suppression on the signal if the background noise is below the at least one threshold, and performing noise suppression prior to echo cancellation on the signal if the background noise is above the at least one threshold.

METHOD AND APPARATUS FOR ROUTE DISCOVERY WITHIN A COMMUNICATION SYSTEM
During route discovery in an ad-hoc communication network, an overlay transceiver (104) determines a plurality of "seed" nodes that lie between the source and the destination node. The seed nodes are notified of the desire to discover a route between the source and the destination node. Once notified, the seed nodes immediately broadcast route discovery messages. All nodes (101) within the underlay communication system (110) periodically listen for route discovery messages. If any node within the underlay communication system (110) receives a route discovery message having the same route identification, route information between the two seeds will be provided to the overlay transceiver (104), giving the overlay communication system a "path" between the seeds. Once the overlay transceiver (104) receives route information between all seeds, it then determines an appropriate route between source and destination devices, and broadcasts this information to the source and the destination devices.
To address the need for choosing values of harmonic noise weighting (HNW) coefficient (.epsilon.p) so that the amount of harmonic noise weighting can be optimizex, a method and apparatus for performing harmonic noise weighting in digital spech coders is provided herein. During operation, received speech is analyzed (503) to determine a pitch period. HNW coefficients are then chosen (505) based on the pitch period, and a perceptual noise weighting filter (C(z)) is determined (507) based on the harmonic-noise weighting (HNW) coefficients (.epsilon.p).

METHOD AND APPARATUS FOR CONTROLLING ACCESS TO A MULTIMEDIA BROADCAST MULTICAST SERVICE IN A PACKET DATA COMMUNICATION SYSTEM
A communication system (100) determines whether to establish a point-to- multipoint communication or a point-to-point communication for conveyance of Multimedia Broadcast Multicast Service (MBMS) data based on a number of mobile stations (MSs) (102-104), both idle mode and maintaining an active connection, serviced by the system and subscribed to an MBMS service. The system. broadcasts (306) a control message that includes an access probability factor. In order to avoid overloading the systern with responses to the control message, MSs maintaining an active connection ignore (506, 508) the control message while idle mode MSs determine (506, 512) whether to respond based on the access probability factor. The system compares (310) a number of received responses to a threshold and determines whether to establish a point-to- multipoint communication (312) or a point-to-point communication (322) based on the comparison. The system also adjusts (314, 330) the access probability factor based on the number of responses.

SYSTEM AND METHOD FOR PROVIDING KEY MANAGEMENT PROTOCOL WITH CLIENT VERIFICATION OF AUTHORIZATION
A method and system for providing a client (102) with a copy of the authorization data that can be accessed and used by the client. The method is well~suited to key management protocols that utilize the concept of tickets. Two copies of the authorization data, a client copy and a server copy, are included within and forwarded to the client where the client is requesting a ticket for a specific application server (106). The client is capable of accessing the client copy of the authorization data such that the client can verify requests, and determine authorization of use for content and/or services requested.

METHOD AND SYSTEM FOR PROVIDING THIRD PARTY AUTHENTIFICATION OF AUTHORIZATION
A method and system (100) for providing third party authentication when requesting content and/or services from an application server (106). The method is applicable to key management protocols that utilize the concept of tickets. The method and system include a client (102) being coupled with a third party application server (107), wherein the client submits a request for content from the third party application server and the third party application server returns requested information and corresponding authentication. The client further couples with a first application server (106), wherein the client submits a key request (KEY_REQ) including the third party server information and corresponding authentication to the first application server. The first application server authenticates the third party server information and verifies client authorization based on third party information. The first application server returns a key reply (KEY_REP) if the third party server information is authenticated and client authorization is verified.
