GMSK的调制解调原理分析

混合预编码的数字预编码矩阵和模拟预编码矩阵的代码(mm-wave hybrid precode.including bd precode and analog precode)

this is a code that shows QAM consetellation with data repetition (3 time repetition) the transmitted signal goes through flat fading Rayleigh channel

AM调制与解调，信息信号和载波信号经过AM调制并加噪得到AM信号的频谱，再经过带通滤波器，相干解调，低通滤波后得到解调后的信号。(AM modulation and demodulation, information signal and carrier signal through AM modulation and noise to get the spectrum of AM signal, then through band-pass filter, coherent demodulation, low-pass filter to get the demodulated signal.)

A Comparison Between the Centralized and Distributed Approaches for Spectrum Management

OPC技术在自动化监控系统的应用,实现语言是VB(OPC technology in the automated monitoring system to realize the language is VB)

几个关于MIMO雷达的仿真程序，对学习相关内容的人有些帮助。(Several of the simulation program about MIMO radar to the study of relevant content people some help.)

该工程实现对单载波系统QPSK的频偏估计算法。调相信号在接收机相干解调时需要同频同相的参考载波，而发射机和接收机之间往往存在频率偏差，为了消除这种误差，必须在软件层面实现。使用了QPSK四相调制的信号特点进行载波频偏估计，经验证，效果较好。(This project implements frequency offset estimation algorithm for single carrier system QPSK. The phase modulation signal needs the same frequency reference carrier in the coherent demodulation of the receiver, and the frequency deviation often exists between the transmitter and the receiver. In order to eliminate this error, it must be implemented on the software level. The carrier frequency offset estimation is carried out by using the signal characteristics of QPSK four phase modulation.)

说明：  在E.C.Levy的“光电振荡器建模”一文中，利用MATLAB函数编写了单回路OEO仿真程序。为了说明它的用途，我们生成图2，4，5，8和11。(The single-loop OEO simulation is written by using MATLAB functions)

不错的客户端连接程序，希望大家喜欢，里面是一个客户端的程序，一会会提供服务端的程序(good client procedures in the hope that everyone likes, there is a client process, will provide a service side of the process)
