摘要
智能天线波束赋形技术能很好地抑制小区间干扰,联合检测只能抑制小区内的多址干扰[1]。在TD-SCDMA系统上行链路实现了智能天线波束赋形与联合检测的算法结合,并按照标准3GPP25.996[2]的信道环境做了仿真,加入小区间干扰,仿真结果表明,智能天线与联合检测的结合能同时抑制小区内多址干扰和小区间干扰。
Beamforming of smart antenna can eliminate the intercell interference, but joint detection can only eliminate the multiple access interference in the cell. This document presents a new method of combining beamforming of smart antenna with joint detection, and makes the simulation according to the channel environment of 3GPP25. 996. Intercell interference is also considered in the simulation. The result shows that the new method cannot only eliminate the multiple access interference in the cell but also the intercell interference.
