Abstract :
In this paper, we have considered a 2 × L multiple input multiple output (MIMO) system employing Alamouti coding at transmitter and switch and examine combining (SEC) at receiver. At first, analytical expressions for capacity and outage probability, in Rayleigh fading channel, are found. Next, the symbol error rate (SER) for M-ary phase shift keying (MPSK) modulation is calculated. The derived expressions are in closed-form and conform to the simulation results. For more than two (L >; 2) receiver antennas, SEC performs significantly better than the traditional switch and stay combining (SSC).
