摘要：

Performance of Bit Interleaved Space-Time Coded Modulation (BI-STCM) with Iterative Decoding is discussed over fast correlated Rayleigh and Rician fading channels. Asymptotic BER is analyzed through a general and tight error-free feedback bound (EF bound). The convergence to the EF bound and the accuracy of the prediction is verified by simulations. It is observed that on the sixth iteration, the performance almost reaches the theoretical bound in the range of 7-8 dB for Alamouti Space-Time Code (1 Receive antenna).
