Abstract: In this paper, particle swarm optimisation (PSO) algorithm based interference reduction is proposed in multiple input multiple output (MIMO) using wide-band code division multiple access (WCDMA). During transmission MIMO network may get interfered by some interference such as co channel interference and adjacent channel interference. To reduce these interferences many algorithms have been proposed in previous research. Further improve the performance of the MIMO-WCDMA network and reduce the bit error rate (BER) an optimised algorithm is proposed. Simulation results of this paper show that bit error rate (BER) is reduced and also throughput of the network also improved.

Keywords: particle swarm optimisation; PSO; multiple input multiple output; MIMO; wide-band code division multiple access; WCDMA; bit error rate; BER.
