  1. Cdma ( code division multiple access ) is a promising technology for future mobile communication system because of its several features with which other multiple access technology can not compare : higher efficiency of frequency allocation, robust anti - multipath effect, macro diversity, mitigating interference, soft capacity, low power, soft handoff, simple frequency design, easy access, and so on

    碼分多址接入（ cdma : codedivisionmultipleaccess ）方式以頻譜利用率高、抗多徑、抗干擾、軟容量、低功率、軟切換、宏分集、頻率規劃簡單、用戶接入方便等其它多址技術不可比擬的優越性被認為是未來移動通信系統的理想接入技術之一。
