采用串行干扰消除的CDMA蜂窝系统中的跨层资源管理

Cross-layer resource management in CDMA cellular systems with successive interference cancellation

在采用串行干扰消除的CDMA蜂窝系统中,资源的稀缺性以及不同的译码顺序导致不同的系统性能等因素的存在,使得研究联合译码顺序调整的跨层资源管理很有必要。讨论了这类系统中无线资源管理的研究现状,包括功率控制、速率分配、容量分析与接纳控制等方面,分析了当前研究的局限性;给出了跨层资源管理的进一步研究方向。

In CDMA cellular systems with successive interference cancellation （SIC） ,cross-layer resource management need to be studied by taking into account the adjustment of decoding orders due to scare resources and different decoding orders resulting in different system performance. This paper first discussed the research status of radio resource management in this kind of systems,including power control,rate allocation,capacity analysis and admission control,and then analyzed the limitations of current research. Finally,proposed the further research direction of cross-layer resource management.
