To improve the spectrum efficiency, this paper considers the multiuser detection with the MU-MIMO technology for multiuser MIMO-OFDM system uplink with the same subcarrier shared by multiple users. A low complexity mu...
为了促使Ad-hoc网络中的"自私"节点进行合作,提出了一种基于博弈论和粒子群优化的协作算法(Nash Bargaining of game theory and particle swarm optimization,NGPSO)在算法的第一阶段,源节点通过对中继节点转发的数据进行价格补偿,从...
