Abstract-- The so-called receiver multiuser diversity aided multi-
stage minimum mean-square error multiuser detector (RMD/MS-MMSE
MUD), which was proposed previously by the author, is investigated
in the context of the direct-sequence code-division multiple-access (DS-
CDMA) and space-division multiple-access (SDMA) systems that employ
in- and quadrature-phase (I-Q) modulation schemes. A detection scheme
is studied, which is operated in real domain in the principles of successive
interference cancellation (SIC). The concept of noise recognition factor
(NRF) is proposed for explaining the efficiency of SIC-type detectors and
also for motivating to design other high-efficiency detectors. The achiev-
able bit error rate (BER) performance of the RMD/MS-MMSE MUD is
investigated for DS-CDMA and SDMA systems of either full-load or over-
load, when communicating over Rayleigh fading channels for the SDMA
and over either additive white Gaussian noise (AWGN) or Rayleigh fading
