从概念上来说,匹配滤波器简言之是一个线性网路,检测混在高斯噪声中的信号时,匹配滤波器均方误差减至最小。在检测之前,匹配滤波器使信/噪比变为最大,以便使接收波形 Si(t)~3
Conceptually, a matched filter is simply a linear network that minimizes the mean square error of the matched filter when it detects a signal mixed in Gaussian noise. Before detection, the matched filter maximizes the signal / noise ratio so that the received waveforms Si (t) ~3
