this code plots the performance of BPSK modulation in various fading channels like rician, rayleigh and awgn channels.

QAM 16 Constellation, Gray Coding, Average energy, Symbol errors are done for reference and 19th constellation.

这个是Preisach模型的基本模块，Jenkin的源代码。这种基本算子的线性组合就构成了preisach模型。(This is the basic module of the Preisach model, Jenkin' s source code. A linear combination of this basic operator constitutes the preisach model.)

对现有数字调制方式识别类型有限的问题，提出一种基于星座图的分类算法。算法首先利用盲均衡技术克服信道的多径效应与系统问步误差，再对信号减法聚类，提取聚类中心与理想星座图模型进行匹配，从而实现MAsK、MPsK、MOAM等调制方式的识别。(Existing types of digital modulation recognition of limited problem, a classification algorithm based on the constellation. Firstly, the use of blind equalization technique to overcome the effects of multipath channel and ask-step system error, and then the signal subtraction clustering, cluster centers extracted constellation model and the ideal match to achieve MAsK, MPsK, such as modulation recognition MOAM.)
