An ant colony optimization (ACO) based multiuser detection (MUD) for the receive-diversity aided space-time block coding (STBC) systems is proposed. The ants are allowed to deposit pheromone based on the concept of Pareto optimality, using the information from the individual antennas independently. Simulations show that detector employing the Pareto optimality has enhanced bit-error-rate (BER) performance. Beside, the proposed ACO-MUD not only outperforms the genetic algorithm approach in BER performance, but also avoids the BER floor that the genetic algorithm encountered.
