文章对多径衰落信道条件下空时2D-Rake接收机各种结构的抗单音干扰性能进行了全面的分析与比较,结果表明在各种结构中,空时联合MMSE合并结构具有最优的抑制单音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,在单音干扰情况下仅需较少的接收天线即能达到较好的性能。即使在多个单音干扰同时存在的情况下,只要干扰个数不大于系统自由度,该种结构仍能获得较好的干扰抑制效果。
The anti-monophonic interference performance of various structures of space-time 2D-Rake receiver under multi-path fading channel conditions is analyzed and compared. The results show that in all kinds of structures, space-time combined MMSE has the best Suppression of single-tone interference and multi-path fading against channel performance, which is less affected by the interference power, in the case of single-tone interference with fewer receive antennas that can achieve better performance. Even in the case of multiple mono-tone interferences, the structure can still achieve good interference suppression as long as the number of interferences is not greater than the degree of freedom of the system.
