摘      要：In this paper, the closed form expressions of symbol error rate (SER) are derived for a space time block coded OFDM system subject to carrier frequency offset (CFO) under frequency-selective generalized fading scenarios. Apart from this, the effect of imperfect channel state information (CSI) is also taken into account for error rate analysis. The derived expressions are valid for any family of fading PDF5 and the results of zero CFO with perfect CSI are found to be a special case. Numerical results are verified by extensive simulations.
