    Asymptotic RZF cooperative beamforming algorithm based on energy efficiency by Yinghui ZHANG, Biao ZHANG, Xiaoting LU, Yang LIU

    Published 2019-10-01
    “…A low complexity asymptotic regularized zero forcing cooperative beamforming algorithm based on energy efficiency in heterogeneous massive MIMO system was proposed,aiming at the problem that the current multi-flow regularization zero forcing beamforming algorithm sets the power constraint of each antenna in the regularization term as a fixed value and ignores the influences of factors such as the number of antennas,the number of users and QoS.The algorithm selects the optimal antenna power constraint set through the optimization method,and the optimal beamforming was asymptotically ob-tained to balance the interference among users to achieve the optimal energy efficiency,considering the impact of the number of antennas and users with the constraints of the antenna power and QoS.In view of the importance of backhaul in massive MIMO system,a backhaul power consumption model and the impact of backhaul power consumption on system performance was analyzed.Analysis and simulation results show that the proposed algorithm has great improvement of the performance,especially when the number of antennas is large.The algorithm is close to optimal performance,especially suitable for massive MIMO system of next generation communication.…”

    Properties of virtual MIMO signal and interference in cooperation cognitive networks by Xu BAO, Tie-cheng SONG, Lian-feng SHEN

    Published 2012-05-01
    “…A virtual MIMO scheme based on cooperation of the prim and secondary users was proposed in the wireless cognitive networks.The tight upper and lower bounds about the complimentary cumulative distribution function of the virtual MIMO signal and interference were derived.The asymptotic distributions of the bounds were also obtained.The theoretical derivations and numerical simulations testified that the upper and lower bounds had the same asymptotic distribution.The numerical simulation results reveal that the virtual MIMO technique improves the anti-interference ability of the primary signal.…”
