计算信号的峰值，平均值和均方根值，并从txt文件直接得到(get the top and its mean value)

通过此程序能够实现一个序列的自相关运算或两个序列的互相关运算，在扩频通信中应用广泛(Through the self-correlation operation of this program is to achieve a sequence or two sequences of cross-correlation operator, widely used in spread spectrum communication)

这是VAD有关代码。也就是说为了在音声中找到activity voice 用GAET方法来决定阈值，然后判别了无音区间。(voice activity detection)

本程序可仿真IEEE802.16e LDPC编解码器，程序设计原理见本人如下专著。 [1] 肖扬著, Turbo与LDPC编解码及其应用,人民邮电出版社，2010. [2] 肖扬著, MIMO多天线无线通信系统，人民邮电出版社，2009。 本程序只用于科研，不得用于其它场合。(The program can simulate LDPC codec with IEEE 802.16e LDPC of the size 2256*4512, and 1/2 code rate. Copyright (C2010-2015) Yang XIAO, Beijing Jiaotong University, Nov.3, 2010, E-Mail: yxiao@bjtu.edu.cn. Current Version Published: 2010-11-3 In my following books, I derived the algorithm of constructing the parity check matrices of IEEE 802.16e LDPC. [1] Y.
