CDMA Multiuser Detection Based on Improved Particle Swarm Optimization Algorithm
Nan Ping Liu, Fei Zheng, Ke Wen Xia · Applied Mechanics and Materials · 2011
CDMA multiuser detection (MUD) is a crucial technique to mobile communication. We adopt improved particle swarm optimization (PSO) algorithm in MUD which incorporates factor and utilizes function to discrete PSO. Comparison of BER and near-far effect has verified its effectiveness on multi-access interference (MAI). The algorithm accelerates the convergent speed meanwhile it also displays feasibility and superiority in case simulation.
