中文说明：此代码基本上是为了学习的目的，是学习的概念，信道估计，噪声与不同的方差和概率误差计算。我创建了一个采用BPSK使用比特序列总长度是1000位，在噪声信道传输和接收。在接收比特误码率后，再对不同的噪声进行重复，并对不同的噪声进行重复计算。最后，我们比较了所有通道的性能，这将有助于你清晰地清楚你的噪声，信道，错误的概率，检测和估计的概念。谢谢
English Description：
This code is basically for the purpose to learn the concepts of channel estimation, Noise with different variance and probability error calculations. I created a bit sequence using BPSK total length used is 1000 bits.That is transmitted over a noisy channel and its received . After receiving bit error rate is calculated.Again the part is repeated for different noises with different variance. At the last we compared the performance of all the channels.It will help you out to clear your concepts about noise , channel , Probability of error, Detection and estimations. Thanks
