Multiuser Signal Detector for Multipath Fading Code Division Multiple Access Channels

摘要

Under the assumption of Rayleigh frequency selective fading channels;we analyze the detection mechanism in CDMA communication systems and a new concept-equivalent left section and equivalent right section of the user's normalization spread spectrum waveform is proposed firstly in this paper.According to this concept,a new algorithm is derived which can simultaneously eliminate the cochannel interference and resist the multipath fading.
