说明：  关于蒙特·卡罗方法的一个简单算例；用来计算椭圆面积(Monte Carlo method)

this code explains the performance of BPSK and QPSK modulation techniques in terms of there bit error probability. this code plots the simulated bit error rate of bpsk and qpsk in terms of SNR. both modulation techniques are explained in RAYLEIGH fading channel.
