Abstract

In this paper, the effect of an imperfect channel estimation and carrier frequency offset on the performance of a space-time block coded (STBC) OFDM system is investigated. For the performance evaluation, the average bit error rate (BER) expression is derived in the presence of the imperfect channel information including both the inherent estimation error and the imperfect windowing error derived in a mismatched channel separation. From presented results, the inherent channel estimation error is a dominating term in the system performance, compared to other parameter imperfections.
