Beam propagation method code in Matlab.

雷达中频目标回波，线性调频脉冲多普勒起伏模型！希望对亲有帮助！！(IF radar target echo Doppler downs chirp model! I hope to help the pro! !)

用于生成FPGA中RAM所需要的初始化文件dds.mif,此文件生成的是余弦波形。(This document of .m can generate document of .mif to provide data for RAM of FPGA.)

基于二阶统计量的SOBI算法，适用于盲源分离(SOBI algorithm based on second-order statistics for blind source separation)

这是关于可变分数延时滤波器的设计，适合初学者使用，相信对初学者有很大帮助(This is the variable fractional delay filter design, suitable for beginners to use, I believe there is a great help for beginners)

超宽带中的频谱检测算法的MATLAB实现，实用价值高。(Ultra-wideband spectrum detection algorithm in the MATLAB realization of high practical value.)

说明：  该程序包中包含传统拉普拉斯金字塔分解和重构的matlab代码，以及测试程序(The package includes the traditional Laplace pyramid decomposition and reconstruction of matlab code, and testing procedures)

计算了贝塞尔函数的一阶导数的零点。 更新BessDerivZerosBisect.m这些变化： 1。允许对m= 0 2。允许用户指定特定的m和k值理想。 3。允许公差输入参数 4。使用一个表的查找能为m和k的小值接近初始化 5。添加错误检查 6。计算衍生w.r.t.以X而不是w.r.t.米（虽然老方法的工作也。）(Calculates the zeros of the first derivatives of Bessel function. Updates BessDerivZerosBisect.m with these changes: 1. Allows for m = 0 2. Allow the user to specify the particular m and k values desired. 3. Allows for a tolerance input parameter 4. Uses a table look-up to get closer initializations for small values of m and k. 5. Adds error checking 6. Computes the derivative w.r.t. to x rather than w.r.t. m (although the old method works, too.))

粗糙惩罚算法，此算法能够分辨光谱数据中的坏点，并对坏点加以惩罚，即减小该点的权重值，从而使得数据更加真实平滑。(Roughness Penalty Smoothing)

it involves bask,bpsk,decomposition andlbp code,qpsk, and bpsk demodulation
