说明：  实现了hu的七个不变矩，matlab实现，很实用(This code realize Hu s moment by matlab)

FFT及应用实验报告,用matlab对fft进行仿真，包括图形和代码(Application of FFT and experimental reports on the fft using matlab simulation, including graphics and code)

用MATLAB编码不归零码和HDB3码之间的转换的编码部分(MATLAB code is not used and the HDB3 code NRZ coding part of the conversion between)

可以用于模拟lbm方法的matlab相关程序(Lbm method can be used to simulate the procedures matlab)

基于<<Discrete Fractional Fourier Transform Based on Orthogonal Projections》的分数阶傅立叶变换(Fractional fourier transform based on 《Discrete Fractional Fourier Transform Based on Orthogonal Projections》)

说明：  与连续信号的解调相比，短时突发信号持续时间短，不适用性能良好的反馈环路算法，需要使用前向幵环算法。与一般突发信号相比，短时突发信号没有训练序列、同步头等辅助信息，所有参数需要利用有限的数据估计。与合作通信相比，盲接收信号参数的初始偏差较大，估计范围小的算法不适用。每个突发包的数据有限，解调过程不允许丢失任何符号。(Compared with the demodulation of continuous signal, short burst signal has a shorter duration and is not suitable for the feedback loop algorithm with good performance. Forward loop algorithm is needed.)
