A joint antenna and user selection scheme for multiuser MIMO system
چکیده انگلیسی


• In this paper, we present a low-complexity algorithm for real-time joint user scheduling and receive antenna selection (JUSRAS) in Multiuser MIMO systems.
• The computational complexity of exhaustive search for JUSRAS problem grows exponentially with the number of users and receives antennas.
• We apply binary particle swarm optimization (BPSO) to the joint user scheduling and receive antenna selection problem.
• In addition to applying the conventional BPSO to JUSRAS, we also present a specific improvement to this population-based heuristic algorithm; namely, we feed cyclically shifted initial population, so that the number of iterations until reaching an acceptable solution is reduced.
• The proposed BPSO for JUSRAS problem has a low computational complexity, and its effectiveness is verified through simulation results.
