说明：  OFDM系统功能仿真，很好很强大，嗯嗯嗯(OFDM system, functional simulation, very good very strong, er er er)

该程序集是matlab数值计算程序，包括很多种类(The assembly is the Matlab numerical calculation procedures, including many types of)

只需要使用Matlab 就可以播放 wave 檔.不需要Media Player或音樂撥放軟體.(Use Matlab to play wave file. This is an example to play 1k tones by using Matlab.)

PROGRAM OF PRINCIPAL COMPOSANTE

说明：  包含了阵列信号处理的常见算法的MATLAB仿真，比较全(Contains the common array signal processing algorithms MATLAB simulation to compare the whole)

利用J-A模型求解磁滞回线时，使用龙格库塔四阶方法求解微分方程的代码，并可以将求解结果直接绘制成磁滞回线图像(When the J-A model is used to solve the hysteresis loop, the Runge-Kutta fourth-order method is used to solve the differential equation code, and the solution result can be directly drawn as the hysteresis loop image)

基于人工神经网络的信号预测在Matlab中的研究与实现，有具体的例题，同时包含详细的m文件代码(Signals based on artificial neural network prediction in Matlab, research and implementation, with specific examples, while m-file code contains detailed)

设计一个四用户的扩频通信系统，扩频增益为N=16，采用Walsh码进行直接序列扩频，BPSK调制，无线信道为AWGN信道。在接收端进行解扩，解调，判决，通过仿真得到其中一个用户的误比特率与信噪比的仿真结果。(Designed a four-user spread spectrum communication system, spreading gain for N = 16, using Walsh code Direct Sequence Spread Spectrum, BPSK modulation, AWGN channel for the wireless channel. At the receiving end for despreading, demodulation, judgments, through the simulation to be one of a user' s bit error rate and SNR of the simulation results.)
