ZFFT

主要是BURG法对声信号进行谱估计的程序。 还有利用BURG法求AR模型系数(BURG mainly on the sound signal spectral estimation process. BURG method are the use of AR model coefficients)

qpsk transmiter with qpska modulator QPSK is a method for transmitting digital information across an analog channel.Data bits are grouped into pairs, and each pair is represented by a particular waveform, called a symbol, to be sent across the channel after modulating the carrier.

提供了外文文献具体解释了HHT得缺陷之一，模态混叠现象。 通过matlab的仿真具体解释了HHT用于信号分析时出现模态混叠的临界点。(english papers to explain one of the limitations of HHT-MODE MIXING simulation base on MATLAB provide graph to improve that limitation)

this source code is very good

通訊方面眾多原始碼，包含OFDM.CDMA.STTC.Power Control.Antenna Array方面的原碼，用於調變.解調.編碼.傳送.功率控制等方面。(Source of many communications, including aspects of OFDM.CDMA.STTC.Power Control.Antenna Array original code used for modulation. Demodulator. Coding. Transmission. Power control and so on.)

一般来说，matlab中没有现成的工具箱来解决整数规划问题，但可以利用分支界定法来编程实现(Generally speaking, matlab no ready-made kit to solve the integer programming problem, but can use the branch as defined in law to Programming)

该幻灯片详细阐述了matlab函数的绘图函数，及函数详细的应用例程！(this book tell us how to use matlab software to draw picture!)

pca 轴承故障诊断程序，有数据，有运行结果(pca Bearing fault diagnosis program, data, have the operation results)
