QPSK_raised cosine

大规模MIMO信道容量分析，主要分析了BS和MS天线数不断增大时，对信道容量的影响。(The analysis to Massive MIMO channel capacity as the antennas of BS and MS grow up. )

给出了分数阶傅里叶变换的具体实现程序，阶数可调。该程序实现是根据一篇通信学报上的论文做的。同时提供了OFDM系统在不同信道估计技术下的误码率以及多径信道下的性能。对于想研究基于分数阶傅里叶变换的OFDM系统的人有一定帮助。(The codes for fractional fourier transform (frft) and its inverse way are given according to a published paper in Journal of Communication. The power is adjustable. In addition, two programms of OFDM system simulation under different channel estimate technique and multipath are offered. Therefore, such file packet is of use for those who have interests in studying OFDM based on frft)

AF，DF，CC,三种基本协作方式仿真程序(Simulation of three basic collaborative approach)

本程序是对低密度奇偶校验码的校验矩阵的源程序，相信会对研究ldpc码的人会很有帮助的(This procedure is a low-density parity check matrix of code source, I believe that research on LDPC codes will be very useful)

LLL格基规约的matlab算法程序，能够实现向量的格基规约(matlab code for LLL lattice reduction)

运行在QT 上，而且基于TCP协议上的，连接服务器的服务端口(TCP-based server service ports on QT)

角谱--VCSEL发出的光，经过透镜耦合进入光纤，仿真给出光由VCSEL进过透镜进入光纤的过程(Angular spectrum)

This program simulates the bit-error-rate (BER) performance of OSTBC with L=4 antennas over the frequency flat Rayleigh block fading channel The code is developed for real orthogonal design, code rate 1/2 modulation- 16 QAM with gray coding resulting in 2 bits/sec/Hz.
