说明：  这是外汇活动中的一种 可以从多种货币的汇率差异中,获得利润(This is one of the foreign exchange activities that can be profited from the exchange rate differences of multiple currencies.)

简单的OOK调制程序，很不错的哦，大家来吧！(Good OOK modulator program)

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.)

说明：  数字通信系统的仿真，全matlab代码，实测可用(Digital communication system simulation, full matlab code, measurement available)
