Short-Protograph-Based-LDPC-Codes-

This is a Matlab v6.5 implementation of the Lagrange interpolation algorithm.

说明：  最短路径的通用程序，matlab，在网上整理的，有些问题，需要进一步调整。(The shortest path of the general program, matlab, online finishing, some issues require further adjustment.)

alpha稳定分布的函数。该分布是一种连续概率分布，其概率密度比高斯分布概率密度有更厚的拖尾，是一类适用范围很宽的随机信号模型，比高斯分布有更广泛的适用性。(Alpha stable distribution function. This distribution is a continuous probability distribution, the probability density are thicker than gaussian probability density trailing, random signal model is a kind of very wide application scope, has wider applicability than gaussian distribution. )

matpower工具箱中最小潮流计算的matlab代码(matpower minimum flow calculation toolbox matlab code)

自己编的welch方法用于功率谱估计的算法代码，希望有用。(Welch their series method for power spectrum estimation algorithm code, I hope useful.)

fastica 独立成分分析的matlab代码(Independent Component Analysis FastICA matlab code)

BPSK 与QPSK 调制解调系统的Matlab 仿真程序,发送滤波器与接收滤波器均为根升余弦滚降滤波器；信道噪声为加性高斯白噪声 绘制BPSK 与QPSK 调制下的误码率与信噪比曲线图，并与理论曲线进行对比(BPSK and QPSK modulation and demodulation system Matlab simulation program, send and receive filters are root raised cosine filter roll-off filter channel noise, BER and SNR draw BPSK and QPSK modulation under additive white Gaussian noise than the graph and compare with the theoretical curve)

说明：  很简单的matla帧差法的代码。。。。。。。。。。。。(Very simple matla frame difference code)

homomorfic filter image

Function uses Standard Hough Transform to detect circles in a binary image. According to the Hough Transform for circles, each pixel in image space corresponds to a circle in Hough space and vise versa. Upper left corner of image is the origin of coordinate system.
