FIR

说明：  在二值化前,将像素与阈值的误差扩散到周围像素上,提高图像的二值化质量(value of the two former, and pixel threshold value of the error spread to the surrounding pixels, and improve the image quality of two values)

说明：  matlab中的傅里叶变换，线性卷积，循环卷积，在基带等效信号加高斯白噪声信道模型下，BPSK,QPSK,QAM等调制解调的误码率计算。(Do not call any function in the case, resulting in [0,1]uniform distribution of interval random variable matlab program.)
