Noncoherent M-ary Orthogonal FSK Alamouti Space-Time Coding with Antenna Selection

In this paper, we apply the antenna selection to noncoherent Alamouti space-time coding for transmission over a Rayleigh fading channel. We investigated the effect of antenna selection on average bit error probability of noncoherent detection of Alamouti space-time coded orthogonal modulation. The performance is evaluated, through a simulation study, for the cases of a single receive antenna and a dual receive antenna. Results establish the degree of diversity gain that could be achieved with antenna selection.
