Abstract :
Differential unitary space-time modulation (DUSTM) is well established for high data rate communications in the multi-antennas channel without channel state information (CSI). To achieve the channel capacity, a new scheme, which employs the turbo-trellis coded modulation (TTCM) and DUSTM, is proposed in this paper. Simulation results reveal that in the TTCM-DUSTM scheme, around 12 dB coding gain is obtained over the original DUSTM system at the bit error rate (BER) of 10-4
