摘要
对多径衰落信道条件下空时rakeMMSE合并结构的窄带干扰抑制性能进行了分析,结果表明相比其它空时rake合并结构,MMSE合并结构具有最优的抑制窄带干扰和对抗信道多径衰落的性能,它受干扰功率的影响较小,而且该种合并结构仅需较少的接收天线即能获得较好的性能。
The performance of space -time Rake M MSE combining structure for suppressing narrowband interferences is analyzed in this paper.Numerical re sults show that this structure' s performance against narrowband in terference and multi -path fading is the best among all vers ions of space -time Rake receiver and is not greatly affected by the power o f NBI .And through only a few receiver antennas this structure can attain good perfo rmance.
