Abstract
Semianalytic estimation of bit-error-rate (BER) is one of the efficient procedures for evaluating BER for modulation formats having circular constellation with noise component of the decision variable is circularly symmetric with Gaussian distribution. To ensure very rapid simulation run time analytical and simulation techniques are used together unlike conventional Monte Carlo simulation. This technique is demonstrated to estimate BER of SC-QPSK system under Nakagami-m frequency selective fading channel. Finally error rate estimation is extended to system having multiple channel reception using spatial diversity combiners. Our result shows that system performance degrades with increasing value of system parameter.
