介绍了一宽带的数字锁相环的实现方法，欢迎大家踊跃下载 (Introduction of a broadband digital phase-locked loop method, enthusiastically welcomed the U.S. Download)

QPSK调制与解调，并有误码率的分析，加了 信道噪声。(QPSK modulation and demodulation, and bit error rate analysis, the addition of channel noise.)

本文件包括matlab 仿真内容 有 四阶龙库格 函数仿真 等(This document contains the contents of matlab simulation of fourth-order function of simulation cell Long Library)

说明：  傅里叶变换能将满足一定条件的某个函数表示成三角函数（正弦和/或余弦函数）或者它们的积分的线性组合。利用傅里叶变换可对语音信号消噪。(ourier transform to meet certain conditions can be expressed as a function of trigonometric functions (sine and/or cosine functions), or their integral linear combination. Fourier transform to denoising the speech signal.)
