DS-CDMA链路中加入基于子空间的PASTd多用户检测方法。系统中采用m序列阔频，可以通过高斯信道或瑞利信道。可以直接运行得到不同信噪比下的误码率曲线。(DS-CDMA link added Subspace-based multiuser detector PASTd. M sequence used in the system wide-band, Gaussian channel, or by Rayleigh channel. Get different signal to noise ratio can be run directly under the BER curves.)

直扩码分多址DS-CDMA是利用高速的WALSH正交码序列作为地址码，与多用户信息数据相乘得到信息数据的直接扩频信号，再经过BPSK调制后发送出去，经过AWGN无线信道的传输后，在接收端与本地产生的地址码进行相关检测，从中将地址码与本地码一致的用户数据选出，把不一致的用户数据删除。(DS-CDMA DS-CDMA is the use of high-speed WALSH orthogonal code sequences as address code, with multi-user information data has been multiplied by the direct spread spectrum data information signal, and then after a BPSK modulated sent through AWGN channel after transmission, at the receiving end with the locally generated address code associated Detect, which will address code with local codes consistent user data elected to delete user data inconsistencies.)

MIMO中的天线选择，空间调制，空时分组码空间调制，等一些算法的仿真(mimo study- spatial modulation is a rencently developed transmission technique that uses multiple antennes.)

说明：  单脉冲和差波束法测角的matlab代码及支持函数，生成和差波束鉴角曲线，可以直接运行(The matlab code and support function of single pulse sum difference beam angle measurement can generate sum difference beam angle discrimination curve and run directly)

说明：  程序中比较了NOMA和OFDMA在容量方面，附带一篇论文，讲的比较详细(The program compares noma and OFDMA in terms of capacity, with a paper, more detailed)
