How we use Space Time Block code and Space Time Trellis Code?

WebWe concatenate AWGN trellis codes with STBC in order to obtain coding gain. Then we compare the performance of concatenated STBC with STTC by keeping transmit power and spectral eﬃciency ﬁxed. The results are somewhat surprising - with the same number of trellis states (4 and 8), concatenated STBC outperforms STTC for 1 and 2 receive antennas.
