用matlab 进行QPSK 的BER 仿真并与理论值比较,计算使用Naive Code [00 01 10 11] 时QPSK的BER，并与Gray Code 比较,求取8PSK 的Gray Code 下的误比特率BER 的解析解(QPSK,BER,Naive Code,Gray Code, 8PSK)

采用AR法模拟风速，计算时间较短，但精度相对于谐波叠加法略差(AR method using simulated wind speed, the calculation time is shorter, but the accuracy is slightly worse relative to the harmonic superposition)

非局部平均算法是一种自适应的空域滤波算法，可以看作Yaroslavsky滤波和双边滤波算法的改进。(Nonlocal average algorithm is a kind of adaptive spatial filtering algorithm, can be seen as Yaroslavsky filter and the improvement of bilateral filtering algorithm.)
