Abstract

In wireless channels, time-selective fading effects arise mainly due to Doppler shift and carrier frequency offset. In time-selective fading channels, the Alamouti-based decoding scheme has an error floor caused by interference due to time-selectivity. This paper proposes decision feedback detector for the Alamouti scheme to mitigate the effects of a time-selective fading channel. Moreover, we present an evaluation of the average bit error rate (BER) performance of the proposed scheme over time-selective fading channels.
