Space-time block coded (STBC) multiple-input- multiple-output (MIMO) systems in conjunction with orthogonal frequency division multiplexing (OFDM) and multicode spread spectrum techniques can provide flexibility in the diversity-multiplexing gain tradeoff. It is worth noting that multicode operation can provide additional degrees of freedom in the code domain to achieve high data rates. Furthermore,...
In this paper, we present a novel particle swarm optimization (PSO) multiuser detection (MUD) approach for multiple-in-multiple-out (MIMO) systems with space-time block code (STBC). The proposed strategy consider the MUD problem with diversity reception from a multiobjective optimization (MO) viewpoint and develop a Pareto-optimal PSO-based (POPSO) algorithm. By taking advantage of the Pareto-optimal...
In this paper, we propose a near-optimal, reduced-complexity turbo multiuser receiver for space-time block-coded multi-carrier code division multiple access (MC-CDMA) uplink systems over frequency selective fading environments based on particle swarm optimization (PSO) algorithm. The soft-input soft-output (SISO) multiuser detector based on a posteriori probability (APP) algorithm can achieve optimal...
We propose in this paper a near-optimal and reduced-complexity turbo multiuser receiver for space-time block-coded (STBC) multi-carrier code division multiple access (MC-CDMA) uplink systems over frequency selective multi-input multi-output (MIMO) fading channels. Since optimal soft-in soft-out (SISO) multiuser detector based on a posteriori probability (APP) algorithm has an exponential computational...
