Future wireless communication systems trend to provide multi - services to mobile users. cdma technique is adopted by the 3rd generation mobile communication systems due to its flexibility in supporting multi - services. how to keep qos of heterogeneous services and utilize the scarce radio spectrum resources is challenging for 3rd generation mobile communication systems in this thesis we developed a radio resource allocation framework for wireless code division access ( cdma ) networks that support multi - class traffic with different data rates and bit error rate requirements. we proposed a new resource allocation scheme using joint adaptive power control and mmse multiuser receiver in multipath fading system
為移動用戶提供多種業務服務是未來無線通信網路的主要發展方向。由於cdma技術具有靈活支持多種業務的優點，因而被第三代移動通信系統所采納。如何在惡劣的無線傳播環境里以及用戶運動且相互干擾的情況下為為各類業務提供qos保證，同時充分利用珍貴的無線頻譜資源，是基於cdma技術的第三代蜂窩通信系統必須致力解決的問題。
