communication simulation

说明：  详细介绍了基于均匀线阵型的波达方向估计算法，线性旋转不变性子空间方法tls-esprit，介绍了RMSE变化的情况，具有可操作性。(Introduces the DOA estimation algorithm based on uniform linear array in detail, the linear rotation invariant subspace method (tls-esprit), the changes in RMSE and it is operable.)

最大比合并功能实现，简单代码，容易看懂，MATLAB源代码(Functions to achieve the maximum ratio combining, simple code, easy to understand)

说明：  qpsk信号插入导频，使用升余弦滤波器，利用导频估计信道，在simulink中仿真(inset pilot in QPSK signal, use square root raised cosine filters in simulink)

这是一个matlab和optisystem联合调试用的误码率计算程序，里面的文件报过一个可以用optisystem7和optisystem13可以打开的OSD仿真图，还有一个MATLAB计算BER的程序。给出了如何设置系统的大纲。从OptiSystem的电信号输入到Matlab组件。当OptiSystem运行时，它将调用Matlab组件中的M文件，处理数据，然后将所得的电信号导出回OptiSystem。然后将输出信号连接到BER分析仪。经过我调试，文件齐全，放心下载(The attached image gives an outline of how the system should be setup. You should start with inputting the electrical signal from OptiSystem into a Matlab component. When OptiSystem runs, it will call the M-file in the Matlab component, process the data, and then export the resulting electrical signal back into OptiSystem.The output signal is then connected to the BER Analyzer.)

对FELICA在日本的应用情况进行了研究，并对Felica与手机结合的方式进行描述(FeliCa in Japan on the application of the study, and Felica and cell phone to describe the combination of)
