Bit Error Probability of STBC-OFDM System over Correlated MIMO Channels with Channel Estimation Errors

摘要

The effect of channel estimation errors on the symbol error rate of space time block code (STBC) over uncorrelated multiple-input multiple-output (MIMO) channel has been given by Hochwald etc.. On top of that, we derive an exact expression for the bit error probability of the quadrature phase-shift keying modulated STBC coded orthogonal frequency division multiplexing system over correlated MIMO channels. The closed-form BEP formula include the impacts, not only of fading and receiver noise, but also that of the channel estimation errors and spatial correlation occurred at the receiver side.
