自适应波束形成器在CDMA系统中抗干扰技术的研究
Research of Adaptive Beam Former for Interference Suppression in CDMA System
【摘要】 本文对码分多址系统中使用自适应波束形成器抗多址干扰性能作了研究,主要探讨检测在既定方向的有用信号的同时,对其它方向的多址干扰进行抑制并在理论和实际上对系统的抗多址干扰的性能进行了分析模拟.
【Abstract】 In this paper the adaptive beam former for Multiple Access interference (MAI) suppression in CDMA system is presented.To detect signal from a certain direction and suppress MAI in different directions and to improve performance for Multiple Access Interference(MAI)suppression are analyzed and proved in theory and in practice.
