A wireless communication device and the method thereof are disclosed. The wireless communication device in accordance with the present invention includes an integrated protocol layer supporting a first communication protocol and a second communication protocol; a single transceiver operative to transmit and receive signals of said first and said second communication protocols.

Method and device for providing multiple communication protocols with a single transceiver

A method and apparatus for canceling a near-end echo of a far-end signal for each channel of a voice over packet multi-channel communications gateway. The invention applies 'off-the-shelf' coding mechanisms as well as novel coding schemes to provide fixed compression rate and with options to maintain perfect speech integrity on certain processing components, such as network echo canceller, acoustic echo canceller, Voice Activity Detector, Comfort Noise Generation, etc. The off-the-shelf compression algorithm includes LPC-10, G.723.1, G.729A. The alternatives are Wavelet transform, DPCM, and ADPCM, etc.

Coefficient domain history storage of voice processing systems

The present invention provides a register-indirect addressing mode using modulo arithmetic to transpose addresses for digital processing systems. The preferred systems and methods permit direct access of column data, which improves matrix computation significantly. The overhead of transpose mode is minimal because it can be implemented, if desired, by sharing hardware and/or software used in circular buffers. Transpose addressing mode also reduces program size and processor power consumed by reducing the sequence of instruction cycles.
