In wireless communication, multipath propagation results in several fading effect. To equalize such long fading channel traditional single carrier time domain equalization becomes infeasible due to its large computational complexity. Single-carrier frequency-domain equalization (SCFDE) offers low complexity, minimum peak to average power ratio as well as less sensitive to carrier frequency offset compared with orthogonal frequency division multiplexing (OFDM). In this paper we proposed SCFDE combining with space time block coding (Alamouti like scheme) for linear zero forcing equalizer achieves significant diversity gain at low computational complexity over frequency selective fading channel also we show that diversity depends not only on antenna configuration and channel memory but also on data block length and data transmission rate.
