    Performance of FTH-PPM multiple access technology in 60 GHz wireless communication system by Chen SHEN, Xuehua LI

    Published 2017-10-01
    “…Aiming at the problem of multiple access interference in 60 GHz pulse wireless communication system,the performance of system based on FTH-PPM multiple access scheme was studied.Under the IEEE 802.15.3.c channel model,the relationship between the bit error rate performance of the system and the number of frequency hopping codes,the signal to noise ratio and the number of users were analyzed.The characteristics of FTH-PPM multiple access modulation system were studied and compared with TH-PPM and TH-PAM schemes.The simulation results show that the system can meet the required bit error rate by changing the signal to noise ratio,the number of hops and the number of users.At the same time,the BER performance of FTH-PPM is better than that of TH-PAM and TH-PPM.The system can select the appropriate multiple access modulation mode according to the value of the pulse duty cycle.The research will provide technical reference for the application of 60 GHz pulse wireless communication.…”

    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.…”
