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.)

适应多个模式的rs编码，Verilog，选择对应的多项式(RS coding adapted to multiple modes.)

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.)
