Firstly this paper researches present mobile communication technique of enhancing system capacity, next further researches basic principles of tdma and cdma system. based on these researches a new scheme is proposed that let broadband code division multiple access ( b - cdma ) system overlay on an existing narrowband digital cellular system ( i. e. gsm )
本文首先研究了移動通信現有的擴容技術，其次深入研究了tdma系統和cdma系統的基本原理，在此基礎上提出了利用gsm與寬帶cdma系統同頻傳輸實現系統擴容的方案。 -
We also proposed a new call admission control ( cac ) scheme for cdma cellular system that incorporates adaptive power control and mmse multiuser receiver and support multi - class traffic. the call admission control scheme is based on estimation of othercell interference and implemented distributively in each cell. capacity determined by the admission control agrees with the actual system capacity in the simulation. the scheme can achieve high bandwidth utilization and guarantee qos requirements of all the users at the call level
為此，提出了呼叫確認策略，以保證系統中不同業務的所有用戶的qos 。呼叫控制策略在每一小區分佈地進行，通過估計其它小區的干擾確定小區的可用有效帶寬，再根據小區當前的負載決定是否對呼叫請求給予確認。呼叫確認控制可以在呼叫級保證用戶的qos 。 -
Taking uplink as an example, both simplified analysis and intensive computer simulations are presented to offer comparisons among frn enhanced systems with the proposed schemes, with a known channel - borrowing based frequency planning scheme and the conventional cellular system without relaying
同時，相對于側重覆蓋面積的頻譜分配方案，側重於頻譜效率的頻譜分配方案的頻譜復用距離較小，從而有更高的頻譜利用率，其重點在於解決頻譜效率問題。 -
