摘要 针对单业务TDD-CDMA系统的上行用户容量进行了分析,其分析结果对网络规划、准入控制与负载控制等具有重要的理论价值。综合考虑TDD-CDMA系统智能天线、联合检测、非完美功率控制、用户分布密度、时隙上下行分配等因素的影响,建立了一种适用于TDD-CDMA系统的上行用户信干比模型,并利用此信干比模型和高斯近似法给出了上行用户容量的计算方法。与现有方法相比,所提方法包涵的系统因素更加全面,因此提出的方法可以更好地用于分析各种复杂网络环境下的TDD-CDMA系统上行用户容量。 The uplink user capacity for a TDD-CDMA system with a single traffic was analyzed. The analysis results have a great academic significance. By taking account of the effects by the smart antenna, the joint detection, the imperfect power control, the user distribution density and timeslot allocation, a SIR model for a TDD-CDMA system, and presents a calculation method of uplink user capacity with this model and the Gaussian approximation method. Compared with the existing methods, the factors considered are more complete, so the proposed method can be used for the analysis of uplink capacity in a TDD-CDMA system under all kinds of complicated network situations.
