The performance of various iterated soft-input soft-output (SISO) multiuser detection (MUD) techniques is evaluated and compared for the case of overloaded condition for symbol-synchronous uncoded Code-Division Multiple Access (CDMA) systems over Additive White Gaussian Noise (AWGN) channel. We show that, via computer simulation, while the Bit-Error Rate(More)
We present the performance evaluation of a grouped chip-level iterated (CLi) multiuser detection (MUD) technique that is based on Gaussian forcing technique for overloaded synchronous code-division multiple access systems. We confirm that the new grouped CLi MUD can approach the performance of the more complex CLi MUD with brute-force search. Also, we show(More)
A batch Kalman-based blind adaptive multiuser detection (K-BA-MUD) with multiple receiver (Rx) antennas is investigated for asynchronous CDMA systems in the Uplink direction. In this paper, we consider two receiver structures: the Independent and the Cooperative structure. Previous results had stated that the Cooperative structure always outperforms the(More)
