This paper presents the performance analysis of the novel concept of limited Multiuser Detection (MUD) for Direct Sequence Code Division Multiple Accesses (DS- CDMA). The novel concept uses the correlation properties and bit streaming for reduced complexity architecture to meet real time requirement for asynchronous multiuser detection in wireless communication. To mitigate the effect of Multiple Access Interference (MAI), this paper proposes a novel technique of multiplication and subtraction (Multisub) of cross correlation factor with receiving signal at output of matched filter, which is the first stage of Parallel Interference Cancellation (PIC) multistage multiuser detector.
