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

Inhalt:
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.
