Devido à complexidade computacional do detector de máxima verossimilhança ideal (OMD) crescendo exponencialmente com o número de usuários, técnicas subótimas têm recebido atenção significativa. Propusemos a otimização por enxame de partículas (PSO) para a detecção multiusuário (MUD) em sistema assíncrono de acesso múltiplo por divisão de código multiportadora (MC-CDMA). O desempenho do MUD baseado em PSO é quase ideal, enquanto sua complexidade computacional é muito menor que a do OMD. O desempenho do PSO-MUD também demonstrou ser melhor do que o do MUD baseado em algoritmo genético (GA-MUD) no SNR prático.

Abstract: Due to the computational complexity of the optimum maximum likelihood detector (OMD) growing exponentially with the number of users, suboptimum techniques have received significant attention. We have proposed the particle swarm optimization (PSO) for the multiuser detection (MUD) in asynchronous multicarrier code division multiple access (MC-CDMA) system. The performance of PSO based MUD is near optimum, while its computational complexity is far less than OMD. Performance of PSO-MUD has also been shown to be better than that of genetic algorithm based MUD (GA-MUD) at practical SNR.
