This matlab code calculates a bit error rate of OFDM system over a flequency-selective Rayleigh fading channel.

微粒群优化算法，经典的粒子群优化算法，第一参数是适应值函数，因此方便多次使用(Particle swarm optimization algorithm, the classical particle swarm optimization algorithm, the first parameter is the fitness function, so convenient to use many times)

matlab实现信号的相参积累和非相参积累源代码(matlab realization the signal coherent integration and non-coherent accumulation of source code)

比较全面的FSK相关知识文档，含例程和模型。(FSK more comprehensive knowledge of the document, including routines and models.)

群体智能优化：粒子群算法，是一种以鸟群觅食这种社会行为为基础的最佳化寻优技术(particle swarm optimization)

Dark_Channel图像去雾，分割部分采用的是guide_filter而源文献中的Soft_Matting，运算效率有较大提升。输入文件地址及文件名需要自己修改。(Dark_Channel Haze Removal, using guide_filter other than soft_matting.)

模拟退火算法求解TSP问题程序简单效率高，欢迎来完善(Simulated annealing algorithm for solving the TSP program is simple, high efficiency, and welcome to improve)

该实例主要是对离散时间系统建模与仿真。例子是以设计一个数字低通滤波器F（z），从受噪声干扰的多频率混合信号x（t）中获取10hz的信号。希望对研究电磁兼容以及学习MATLAB的学者有所帮助。(The examples are mainly discrete-time systems modeling and simulation. Example is the design of a digital low-pass filter F (z), acquiring a signal 10hz noise interference multi-frequency mixed signal x (t) in. I hope to study electromagnetic compatibility and scholars studying the MATLAB help.)
