| Abstract | The performance analysis of Alamouti space time block code (STBC) based orthogonal frequency division multiplexing (OFDM) is often analyzed on the assumption that the channel is constant over Alamouti code period (two consecutive OFDM symbol block). But when the channel is fast fading, this assumption does not hold good and causes co-channel interference (CCI). Hence, the simple Alamouti detection method is not sufficient to recover the original transmitted signal from the mixed transmitted signals at the receiver side. In this paper, we investigate several detection methods for cancelling the effect of CCI which includes SIC, ZF and DF. Finally, the performances of the above detection method are compared on the basis of symbol error rate (SER) for different mobile speed. |
