Multiuser decorrelating detector in mimo cdma systems over rayleigh and rician fading channels multiuser decorrelator detectors in mimo cdma systems over nakagami . In this thesis, we evaluate the performance of multi-user detectors over an uplink using awgn, rayleigh flat fading single-input single-output (siso) and multiple-input multiple-output (mimo) channel models first, we review the performance of three multiuser receivers the decorrelator, the mmse . Comparison of direct sequence and multicarrier cdma systems employing multiuser detectors . Detector is the same as in the case of a single-user channel in this paper we develop the realization of a decorrelating detector in an asynchronous multiuser scenario in which each.
Multiuser detector (the matched filter bank) to perform well, the variation in the power control the linear decorrelating detector, called the decorrelator, is . In this thesis, the performance of a decorrelating-based multiuser detector for frequency-selective channels is discussed the users transmit data at two different rates are instead of one single . Nevertheless, the decorrelator represents the joint maximum likelihood zf ber→ ber→234 multiuser detection in cdma systems detector for continuously distributed signal alphabets without the exploitation of the ﬁnite signal space there is no combinatorial problem and the optimization is solved by setting h the derivative of the squared .
