快速傅里叶变换函数，自己写的函数，直接用即可，ceps倒频谱分析(fast folier transformation)

这是一种搜索有向圈的算法，广泛被用于图论中，非常地实用(There is a search algorithm to the circle, is widely used in graph theory, very useful)

最小均方算法在DPSK和4QAM中的实现，很有用啊，还有word文档介绍基本原理(least mean square algorithm for DPSk and 4QAM transmission )

vc和matlab混合编程，在vc中调用matlab的函数进行计算和处理，本程序中调用了matlab图像处理函数打开图像并进行灰度处理(vc and matlab mixed programming, matlab function calls are calculated and processed in the vc, the program calls the matlab image processing function to open and grayscale image processing)

用MATLAB编写的语音信号的短时分析，主要包括：分帧、短时能量、短时平均幅度、短时过零率、 LmCPhB函数、短时幅度差、倒谱、复倒谱 lnRrOUM系数计等，是我多年调试通过的程序 (MATLAB prepared with short-term analysis of the speech signal, including: framing, short-time energy, short-term average amplitude, short-term zero rate,LmCPhB function, short-term amplitude difference, cepstrum, cepstral lnRrOUM coefficient meter, etc. , is a program debugging through my years of )

通信原理中功率谱密度的仿真，仿真了不同占空比，等概、非等概双极性矩形随机信号的归一化功率谱密度，并分析不同信号（不同占空比，等概非等概）所包含的频谱分量，有无直流分量和定时分量信息(Communication theory in the power spectral density of the simulation, the simulation of different duty cycles, such as almost, almost bipolar rectangular Non-random signal normalized power spectral density, and the analysis of different signals (different duty cycle, etc. None of the other Summary) contains the spectrum component, with or without DC component and time component information)

QPSK调制解调误码率及误符号率，相干解调，输出的bitber是误码率，symber是误符号率(QPSK demodulator BER and misuse of the symbol rate, coherent demodulation, the output is bitber BER, symber mistakenly Symbol Rate)

BPSK simulation with Matlan

关于线性非线性趋势项去除方法的研究及总结(Items on the linear non-linear trend removal method of research and summary)

仿真2×1瑞利信道，分别考虑三种接收分集技术：最大比合并、等增益合并、选择性合并，并给出误码率比较。(In a one transmitting antenna and two receiving antenna collocate,calculate the bits error rates of the maximum ratio combining,equal gain combining ,selective combining and SISO system)
