AN EFFICIENT MULTI-USER DETECTION SCHEME FOR OVERLOADED GROUP-ORTHOGONAL MC-CDMA SYSTEMS
This paper presents an efficient multi-user detection (MUD) scheme for overloaded MC-CDMA systems. The proposed detection scheme for overloaded system achieves the optimal performance for constant-modulus modulation, e.g., MPSK, and provides near-optimal performance for non-constant-modulus modulation, e.g., M-QAM. Moreover, it has lower complexity than other optimal detection algorithms, especially suitable for group-orthogonal MC-CDMA (GO-MC-CDMA) systems, where group-based technique keeps joint detection size relatively small
