... delay compared with the linear G‐SIC. The advantages of the linear G‐SIC and PIC can be exploited substantially. Originality/value The paper proposes an algorithm that can combat the MAI with less complexity, and also can speed the convergence compared with other detectors. Multi‐user detection...

... estimation approach for IDMA based on expectation maximization (EM) algorithm is also presented. Findings The multi‐user detection (MUD) algorithm in uplink IDMA systems is much simpler than that used in traditional CDMA systems. It is also well known that the orthogonal spreading codes in CDMA can...
