Near-Optimum Multiuser Detectors Using Soft-Output Ant-Colony-Optimization for the DS-CDMA Uplink

In this contribution, a novel soft-output ant colony optimization (SO-ACO)-based multiuser detector (MUD) - namely the MUlti-input-Approximation (MUA) assisted SO-ACO-based MUD - is proposed for the synchronous direct-sequence code-division-multiple-access (DS-CDMA) uplink (UL). The previously proposed conventional ACO based MUDs were unable to provide soft… CONTINUE READING
