觉得不错的几段模糊c均值程序，但需要改改(Paragraphs that good Fuzzy c-means procedure, but changed)

对图像求拉普拉斯变换，分别使用中心为-4、-8其他值均为1的拉普拉斯滤波器(Laplace transform of image, Laplace filter respectively using the center for- 4、-8，other value for 1)

说明：  BPSK信号调制解调，在AWGN与RAYLEIGH信道下的无码性能！(BPSK signal modulation and demodulation in AWGN channel with RAYLEIGH-free code performance!)

该程序源代码实现了CDMA通信系统性能的仿真，用MATLAB实现了直序、跳时、跳频以及M序列，GOLD序列等的产生，及在AWGN和RAYLEIGH环境下误码率的计算(The program source code to achieve the performance of CDMA communication system simulation, using MATLAB realize the direct sequence, time hopping, frequency hopping and M sequences, GOLD sequence generation, and in the AWGN environment and RAYLEIGH BER calculation)

遗忘因子法辨识系统参数，直接可以允许的ＭＡＴＬＡＢ程序(Forgetting factor method to identify the system parameters can be allowed to direct the MATLAB program)

在Matlab的Simulink仿真环境，模拟光伏板输出功率曲线。(In Matlab Simulink simulation environment, the analog output of photovoltaic panels power curve.)

本程序介绍了LTE中信道的基于导频的信道估计，方法经典，值得学习一下(This program introduces the LTE CITIC Road Pilot-based channel estimation, the classical method, it is worth learning about)
