snr_mnm

基于多线程机制的，利用Matlab编写，粒子群优化算法。目标变量采用归一化处理，适用于所有的优化函数。优化函数自定义为fitness(x)。(Based on multi-threading mechanism, the use of Matlab to prepare, particle swarm optimization algorithm. Target variables using normalized treatment applies to all of the optimization function. Since the optimization function is defined as fitness (x).)

matlab的上课课件以及全部m文件，希望大家下载学习。(class courseware, and all the matlab m file, I hope you download the study.)

Angle between two points

说明：   leach协议的matlab仿真(leach agreement matlab simulation)

给出比较少见的16PSK的仿真算法，包括高斯信道，瑞利信道及线性时不变信道。其中，在瑞利信道中，给出了均衡前均衡后比较结果，从中可以看出均衡的效果(is relatively rare in the estimation algorithm, including Gaussian Channel, Rayleigh channel and the linear time-invariant channel. Of these, the Rayleigh Channel, is a balanced balanced ago after the results of the comparison, from which one can see the effect of balance)

this program describes the partical filter and extended kalman filter used to reduce the error to get better accuracy of the position

模仿微信打飞机 的Demo 无bug 希望大家一起学习

说明：  经典BP算法(Basis pursuit)，对稀疏一维信号进行恢复，有详细注解，适合初学者(Basis pursuit algorithm)

matlab新增寻找极值点程序，较老的版本中没有次函数(matlab find new extreme point of procedure, not the older version of the second function)

关于信道估计的基本方法，ofdm基本信道估计，有利于初学者(channel estimation of ofdm system)
