Asymptotic Performance of Coded OFDM with Modulation Diversity and Iterative Decoding
— This paper examines the bit error probability (BEP) of bit-interleaved coded modulation and iterative decoding (BICM-ID) in OFDM systems with modulation diversity (MD) over correlated frequency selective Rayleigh fading channels. A tight bound on the asymptotic error performance is derived for the general precoding over all the N subcarriers, which includes precoding over subcarrier groups as a special case. A design parameter that characterizes the effects of signal constellation, mapping and modulation diversity on the asymptotic performance is then established. Various analytical and simulation results are provided to confirm the tightness of the derived error bound.
