Abstract :
An OFDM system of concatenating trellis coded modulation with space-time block coding is proposed. The analysis of pairwise error probability (PEP) shows that if TCM is properly designed the maximum diversity order of the system is achieved. Compared with the uncoded OFDM system and STTC OFDM system with the same number of states, proposed system significantly improves the performance.
