一个很小和天线计算程序，我觉得非常实用，发上来与大家分享(A very small and the antenna calculation program, I think very useful, the table to share with you)

通过一个光相位调制器的实例，介绍利用Optisystem 中Matlab Component组件联合M atlab实现用户自定义光学组件的方法。对相位调制基本原理、相位调制器理论模型和实现模型的Matlab代码进行分析，介绍如何将用户自定义器件功能代码关联Matlab Component组件进行仿真，并利用自定义的相位调制器对理论分析进行验证。(Through an example of an optical phase modulator, this paper introduces the method of implementing user-defined optical components by using Matlab Component component in Optisystem combined with M atlab. The basic principle of phase modulation of the phase modulator, theoretical model and implementation model of Matlab code analysis, describes how to simulate the user device function code associated Matlab Component components, and the theoretical analysis was verified by using custom phase modulator.)

利用MATLAB进行信道建模仿真，包括SUI模型，Clarke/Gans模型，多径衰落仿真GUI，UWB模型，两径模型，指数PDP模型(MATLAB for channel modeling simulation, including SUI model, Clarke/Gans model, multi-path fading simulation GUI, UWB model, two-path model, index PDP mode)

类似simulink的小程序，在网上找到的，希望对大家有用。。(Similar simulink small program, found on the Internet, we want to be useful. .)

封装了windows操作串口的几个API（CreateFile， ReadFile，WriteFile，SetComState）。串口的读写设置这几个操作都可以简单地只用关键一两个参数就能实现操作。也是一个很好的例子，我写这个之前查了不少资料，感觉非常麻烦，索性发出来给新手们作个样例(Windows serial COM port access class，it includes CreateFile, SetComState，ReadFile，WriteFile，CloseFile)

ofdm程序简单明了，包括ofdm整个过程。应该有借鉴意义。(OFDM straightforward procedure, including OFDM whole process. There should be reference.)

OFDM系统的自适应功率和比特分配算法，实现系统资源的自适应分配（3)－原创(adaptive allocation for OFDM system)

基于深度限幅的OFDM峰均比抑制器的设计（限幅法是最简单直接的一种，以降低误码率性能 频谱畸变和计算复杂度为主要代价。）(matlab OFDM)

matlab中fsk调制与解解调解调方式有相干与非相干解调哟 (matlab fsk modulation and the solution demodulation Demodulation coherent and incoherent demodulation yo)

说明：  对接受到的调制信号的特征提取，用于调制识别(automatic modulation recognition)
