Abstract :
An optimal multi-user MIMO linear precoding scheme based on particle swarm optimization is proposed in this paper. The proposed scheme aims to maximize the system capacity of multi-user MIMO system. This paper explores a simplified function to measure the optimal problem. With the adoption of particle swarm optimization algorithm, the optimal linear precoding vector could be easily searched according to the simplified function. The proposed scheme outperforms the multiuser MIMO linear precoding schemes based on channel inversion and channel block diagonalization methods.
