最小相移键控，正交幅度调制

通信系统仿真原理与无线应用书中matlab源程序(Communication System Simulation Principle and wireless applications matlab source book)

说明：  修正MUSIC算法实现相干信号源的DOA估计算法(amendment MUSIC algorithm coherent signal source DOA estimation algorithm)

这是一个仿真qpsk信号通过不同信道模型（包括单径，多径，莱斯，瑞利平坦等信道）的性能的matlab程序。(This is a simulation qpsk signals through different channel model (including single-track, multi-track, Condoleezza Rice, Rayleigh and other flat Channel) Performance of Matlab procedures.)

Plan separator: the code separate the bit 0 to 7 plans of an eight bits image. This is to allow image analysis and to know the most useful part of the image among its features.

本书介绍了matlab的详细编程方法，很详细，适合初学者看看。(This book describes in detail the matlab programming method, in great detail, suitable for beginners to see.)

计算不同雷达信号的模糊函数，画图，可以自行输入不同的信号序列(Calculate the ambiguity function of different radar signals, draw pictures, and input different signal sequences automatically.)

D2D数据信道代码，包括通信模型建立，资源池确定，资源分配，干扰避免策略，sinr及吞吐量计算等内容(D2D data channel code, including communications model, to determine the resource pool, resource allocation, interference avoidance strategy, sinr and throughput computing, etc.)

说明：  BIRCH (balanced iterative reducing and clustering using hierarchies) is an unsupervised data mining algorithm used to perform hierarchical clustering over particularly large data-sets.[1] An advantage of BIRCH is its ability to incrementally and dynamically cluster incoming, multi-dimensional metric data points in an attempt to produce the best quality clustering for a given set of resources (memory and time constraints). In most cases, BIRCH only requires a single scan of the database.

直角坐标法的潮流程序，关于一个5节点的算例，有数据(Cartesian method of trends program, on a 5-node example, with data)

学习ekf的一个源码，对初学者非常有用，随便下载并交流(Extended Kalman Filter Demo )
