最新版本的数学工具的介绍及使用！不错的软件，已经在向vc靠近！欢迎大家使用！(The latest version of the mathematical tools to introduce and use! Good software, have been around to vc! Welcome to use!)

2元BPSK调制加高斯信道硬判决统计误码率(2 yuan plus Gaussian channel BPSK modulation hard decision error rate statistics)

This is a note talk about Block coding Technique for reduction PAPR.

自己编写的旋转算法，没有用imrotate函数(havne t use the function imrotate of matlab)

lu decomposition using matlab programing

网上复制了一个BP预测的程序自己改了一下，效果不是很好。 P 和T都是往期的数据(Online copy of a program his BP forecast changed a bit, the effect is not very good. P and T are the data to the period)

matlab 中一些很用的代码，数值分析于应用。(matlab code, numerical analysis on the application.)

OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀（CP）可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是，过长CP会使得数据传输效率降低。可以采用最小均方误差（MMSE）信道缩短均衡技术来压缩信道冲击响应长度。(OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than the channel impulse response length before the time-domain symbol. However, long CP will reduce the efficiency of data transmission. A minimum mean square error (MMSE) channel shortening equalization technique may be employed to compress the channel impulse response length.)
