matlab 数字实验， 关于数字信号处理课程matlab的数字实验。(matlab digital experiments on digital signal processing matlab figures experimental courses.)

说明：  qam 信号的产生和解调，以及误码率的计算，内包含多个小程序。(qam signal generation and demodulation, and bit error rate calculation, which contains many small programs.)

挂钩和AOP的是有用的SE（软件工程），可用于obtaion分离技术，将是有用的Matlab的编码器。(Hook and AOP is useful SE (software engineering), can be used to obtaion separation technology will be useful Matlab encoder. )

用自相关法求重构相空间的延迟时间的matlab程序(With the autocorrelation method for the reconstruction phase space of the delay time of the matlab program)

本文主要利用matlab编程工具对直接序列扩频通信的捕获过程进行仿真。仿真主要基于滑动相关法的有关理论,先讨论扩频仿真中起着重要作用的m序列的生成问题,尔后讨论调制信号的产生,然后在信号的捕获中分步讨论,先对捕获的流程进行简单的仿真,再依次加入噪声和多普勒频移后进行捕获仿真(In this paper, using matlab programming tools for direct sequence spread spectrum communication capture process simulation. Simulation of the sliding correlation method is based on the theory, first discuss the simulation plays an important role in spreading the m sequence generation problem, the modulation signal generation and later discussed, and the signal captured by stepping discussion processes the captured first simple simulation, and then followed by adding noise and Doppler frequency shift after the capture simulation)

说明：  matlab中的分数阶工具箱，文件中有两个，一个是的工具箱ninteger，一个是的FOTF(The fractional toolbox in matlab has two files, one is the foreign toolbox ninteger, and the other is the domestic FOTF.)

说明：  根据教科书上已经给出的简单的数学算式，运用matlab编写出简单的代码，计算出结果(According to the textbook has been given a simple mathematical formula, using matlab write simple code to calculate the results)

多用波束形成，性噪比、中心频率都可以修改(The use of beamforming, signal to noise ratio of the center frequency can be modified)
