Abstract :
This paper presents the design of space-time turbo trellis coded modulation (ST turbo TCM). We introduce new recursive space-time trellis coded modulation (STTC) which outperform feedforward STTC proposed by Tarokh, Seshadri and Calderbank (see Trans. Inform. Theory, vol.44, no.2, p.744-65, 1998) and by Baro, Bauch and Hansmann (see IEEE Trans. Commun. Letters, vol.4, no.1, p.20-22, 2000) . A substantial improvement in performance can be obtained by constructing parallel concatenation of recursive STTC and making use of iterative decoding. The new recursive STTCs can be used directly in this scheme. ST turbo TCM outperforms the best known STTC by about 2 dB on slow fading channels and by up to 8 dB on fast fading channels
