  1. Assigning serial different address code to different subscribers, useful signal is taken out of the same time slot and frequence, and is transmitted with one share channel. at received end, system makes use of completed address code from sending end to do correlative check and take out useful subscriber signal. the other address code signals are treated as broadband disturbing signal which is removed. in radio environment of existing variable disturbtion and muti - way declining, expand frequence signal ’ s broadband characteristics can improve system performance obviously. cdma mobile telecommunication system has some better characteristics, such as anti - disturbing 、 anti - way declining 、 secrecy 、 capacity 、 utilizing rate of frequence resource and so on, than other mobile telecommunication system

    Cdma （ codedivisionmultipleaccess ）移動通信系統的技術基礎是基於擴頻技術的碼分多址，通過給不同的用戶分配各自特定的地址碼序列，將處于相同時隙和頻率的用戶信號分離開來，採用共享通道方式傳輸信息。在接收端，系統利用與發送端完全一致的本地地址碼對接收信號進行相關檢測，提取需要的用戶信號，而將其他使用不同碼型的信號視為寬帶干擾而從中剔除掉。
  2. The key is that the head - end emits the guide m sequence, which is non - correlative with any users " address code. the phase of all users address code and the head - end address code are combined with the guide m sequence. every user address code phase can attain after the guide m sequence phase is searched and tracked

    論文所提出的方案是通過前端發射固定的導頻信號，並且在前端和用戶端都把用戶地址碼相位捆綁在導頻相位上，使得用戶在同步捕獲和跟蹤導頻相位后，間接得到用戶的地址碼相位。
