For this and almost every other issues maybe you have, remember to consult with the "Get in touch with Us" portion of this site. How Can I Get Authorization to Reproduce 3GPP2 Materials?
数字信号相乘，由于伪随机码速率快，扩展了传输带宽（伪随机码带宽远大于信号带宽，扩展信号频谱），在接收端，用相同的伪随机码序列
多址接入 ：不同的用户使用不同的扩频码，可以在同一频率上同时进行通信，实现了多个用户在同一频段上的同时接入。
Network Infrastructure: The cellular network infrastructure includes foundation stations, mobile switching centers, and data facilities that control and route EVDO site visitors. Base stations converse with mobile devices, whilst mobile switching facilities manage call routing and control network means.
