Abstract

A framework for analyzing the performance of coded MIMO-OFDM systems over generalized Ricean fading channels is established. Orthogonal space-time block codes and receiver maximum ratio combining, and transmitter beamforming to maximize signal-to-noise ratio at a receiver antenna are assumed. The moment generating function method is applied to obtain the probability of outage, the pairwise error probability, and the bit-error rate of the systems considered. A Prony approximation is shown to be a numerically efficient fading averaging method with excellent accuracy. Bit-interleaved and iteratively decoded turbo product codes, Gray encoded M-ary modulation, and other parameters of the IEEE 802.16 standard are used to illustrate numerical results
