Abstract

An Iteratively Decoded Variable Length Space Time Coded Modulation (VL-STCM-ID) scheme capable of simultaneously providing both coding and iteration gain as well as multiplexing and diversity gain is proposed. Nonbinary unity-rate precoders are employed for assisting the iterative decoding of the VL-STCM-ID scheme. The discretevalued source symbols are first encoded into variable-length codewords that are mapped to the spatial and temporal domains. Then the variable-length codewords are interleaved and fed to the precoded modulator. More explicitly, the proposed VL-STCM-ID arrangement is a jointly designed iteratively decoded scheme contriving source coding, channel coding, modulation and spatial diversity/multiplexing. As expected, the higher the source correlation, the higher the achievable performance gain of the scheme becomes. Furthermore, the performance of the VL-STCM-ID scheme is more than 14 dB better than that of the Fixed Length STCM (FL-STCM) benchmarker at a source symbol error ratio of 10-4.
