Abstract :
Space-time block coded OFDM is capable of achieving substantial diversity gains, while supporting high bit-rates in wireless communications. By concatenating a space-time block coded OFDM scheme with powerful channel codes, the performance of the system can be further enhanced. In this contribution both low-density parity-check (LDPC) coding and turbo coding assisted G2 space-time block coded OFDM is investigated. The achievable performance is studied as a function of the number of iterations, coding delay, code rate and decoding complexity.
