mn_curve

基于振动信号的频域处理算法，主要是细化FFT方面的代码(Based on vibration signal in frequency domain processing algorithms, mainly in refining the code FFT)

多方向灰度变换源代码（本子程序为单方向，多方向修改一下即可）(Multi-directional gray transform source code (book program for single-direction, multi-directional modify click))

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)

分枝界定法的matlab程序,应用于数学模型的整数规划(Matlab program branches to define the law applied to integer programming mathematical model)

matlab中的symerr函数可以求得误码率 只要看下文件中最后那个例子，这个函数你就会用了(matlab in symerr function as long as the error rate can be obtained see next document in this last example, this function you will use the)

对工作目录中已有的数据进行载入（load），数据的调用和存储（save），以及简单画图。(static base use of load and save .)

用精细积分法进行算例，与精确解相比较，求得相对误差值。(Precise Integration Method)

说明：  实现了循环卷积的运算，但是只有结果，没有过程(Cyclic convolution operation realized, but only a result, no process)

显示一张图，point spread function of 1 scatter，需要matlab安装Filed II simulation(show a picture of point spread function of 1 scatter )

用于产生QPSK调制信号的程序。有噪声，并经成型滤波器滤波，很实用(For QPSK modulation signal generator. Noise, and by shaping filter filter, it is practical)
