Abstract

A jointly optimised turbo transceiver capable of providing unequal error protection is proposed for MPEG-4 aided wireless video telephony. The transceiver advocated consists of Space-Time Trellis Coding (STTC), Trellis Coded Modulation (TCM) and two different-rate Non-Systematic Convolutional codes (NSCs). A benchmarker scheme combining STTC and NSC is used for comparison with the proposed scheme. The video performance of the both schemes is evaluated when communicating over uncorrelated Rayleigh fading channels. It was found that the proposed scheme requires about two dBs lower transmit power than the benchmarker scheme in the context of the MPEG-4 videophone transceiver, when aiming for an effective throughput of 2 bits/symbol at a similar decoding complexity.
