摘要
本文在DS-CDMA PCN系统抗干扰性能的分析中,首次提出了用户归一化扩频信号等效左半部分和等效右半部分的分析模型,并在此基础上有效地结合传统扩频通信RAKE接收机的抗多径性能和多用户信号检测器的抗多址干扰特性,得到了一种能同时消除同频干扰和对抗多径衰落的多用户信号检测新方法。
By means of interference analysis in DS-CDMA PCN system, a analytical model concerned with equvalent left section and equvalent right section of the user's normalization spread spectrum signal is proposed firstly in this paper. According to this concept, combined with traditional spread spectrum RAKE receiver for fading channels and some newly multi-user signal detectors for erasing cochannel interference, a new algorithm is derived which can simultaneously eliminate the cochannel interferece and resist the multipath fading.
