matlab 学会如何使用矩阵运算函数和数组运算函数,注意区分矩阵和数组的差别，特别是运算符的差别 了解多项式的创建方法和基本运算(Learn how to use matlab matrix operation function and array operation function, pay attention to the difference of discernibility matrix and array, especially the difference of the operator Understanding of the creation method and the basic computing polynomials)

Consider a BPSK and a QPSK system for the following two cases: 1) The probability that the symbol 1 is sent and the probability that the symbol 0 is sent are all the same. 2) The probability that the symbol 1 is sent is two times than the probability that the symbol 0 is sent. Assume that the noise is Gaussian distributed with mean=0 and  2 = 1.
