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.)

这是看完一本通信仿真手册后我自己写的一点程序，包括ASK FSK PSK的调制和解调程序，不过是比较简单的 ，因为用了公式的()
