TD-CDMA系统中的小区间干扰消除技术

Intercell interference cancellation for TD-CDMA mobile systems

针对TD-CDMA系统中的小区间干扰问题,在接收端联合检测算法(JD)的基础上,具体阐述了一种新的算法,用于同时消除本小区其他用户对本用户的干扰和邻近小区对本小区的干扰,将其称之为全联合检测(全JD)算法,该算法是传统JD算法的一种扩展。仿真结果表明,使用该算法可以有效地消除邻近小区对本小区的干扰,与不使用小区间干扰消除技术相比较,其性能有所提高。

In this paper, a new algorithm which is named F_JD to address the reduction of both intracell and intercell interference in TD-CDMA mobile systems is presented based on the existing algorithm of joint detection （JD）. The simulation is conducted and its results shows that with the existing algorithm of joint detection. The new intercell interference mitigation algorithm has a better Performance in eliminating interference from vicinity
