Abstract	A turbo-detection aided serially concatenated inner trellis coded modulation (TCM) scheme is combined with four different outer codes, namely with a reversible variable length code (RVLC), a non-systematic convolutional (NSC) code, a recursive systematic convolutional (RSC) code, or a low density parity check (LDPC) code. These four outer constituent codes are comparatively studied in the context of an MPEG4 videophone transceiver. These serially concatenated schemes are also compared to a stand-alone LDPC coded MPEG4 videophone system at the same effective overall coding rate. The performance of the proposed schemes is evaluated when communicating over uncorrelated Rayleigh fading channels. It was found that the serially concatenated TCM-NSC scheme was the most attractive one in terms of coding gain and decoding complexity among all the schemes considered in the context of the MPEG4 videophone transceiver. By contrast, the serially concatenated TCM-RSC scheme was found to attain the highest iteration gain among the schemes considered.
