匹配滤波器的源代码，可以实现信号生成的匹配滤波(The source code matched filter, can achieve the matched filter the signal generated)

A Costas loop is a phase-locked loop used for carrier phase recovery from suppressed-carrier modulation signals, such as from double-sideband suppressed carrier signals. It was invented by John P. Costas at General Electric in the 1950s. Its invention was described as having had "a profound effect on modern digital communications".
