DS-CDMA系统中的多用户检测技术
首发时间:2010-09-29
摘要:直扩码分多址技术(DS-CDMA)是第三代移动通信的关键技术。在DS-CDMA系统中,所有用户信号在时域和频域上重叠从而引起互干扰(即多址干扰,MAI)。传统的DS-CDMA信号检测技术独立处理每个用户的信号,与其他用户无关。而在多用户检测技术中,它利用多用户信息来改善各个用户的检测性能。

Multiuser detection for DS-CDMA communications
Abstract:Direct sequence-code division multiple access technology (DS-CDMA) is the key technologies of the third generation mobile communication. At DS-CDMA communications, all of the users signal overlap in time and frequency domain and consequently arouse the interference on each other (ie, multiple access interference, MAI). Conventional signal detection technology for DS-CDMA independently deal with each user's signal, regardless of other users. While, multiuser detection technology utilizes multiuser information to improve the detection performance of individual users.
Keywords: DS-CDMA multiuser detection MAI
