    Blind separation algorithm of PCMA signals with different symbol rates based on DG-PSP by Yi-ming GUO, Hua PENG, Yong YANG, Xue-juan WEI, Hao WANG

    Published 2017-03-01
    “…A blind separation algorithm was proposed for PCMA signals with different symbol rates based on double grid per-survivor processing (DG-PSP).The channel states and two input signal components were treated as two dynamic grids,receiving mixed-signal reconstructed by respectively iterative updating the two groups of grid status,thus achieving blind signal separation.The joint iterative decoding separation structure was focused,and a detailed analysis and comparison under different error estimation of parameters was shown.The complexity of the algorithm is similar to the traditional PSP algorithm.Simulation results show that,a gain of about 2 dB in signal-noise ratio can be obtained after the first iteration at a bit error rate of 10<sup>−2</sup>,and a gain of nearly 3 dB in signal-noise ratio can be obtained after the second iteration.…”

    A low complexity ZF precoding scheme based on weighted Gauss-Seidel in massive MIMO systems by Dong ZHOU, Haiyan CAO, Fangmin XU, Xin FANG, Xiumin WANG

    Published 2019-03-01
    “…In massive MIMO systems,due to inversion of Hermitian matrix,the complexity of the traditional ZF precoding method increases exponentially with increase of the number of users.To solve this problem,a low complexity digital ZF precoding scheme based on weighted Gauss-Seidel (WGS) was proposed.That was weighted addtion the iteration results of previous step and Gausee-Seidel iteration results to accelerate the iterative convergence.The weighting factor was determined by the least mean square sum,and the weighting factor was proved to make the algorithm converge.The simulation results show that the WGS algorithm can approximate the performance of ZF precoding scheme with very few iterations,and reduce the complexity of ZF precoding from O(K <sup>3</sup>) to O(K<sup>2</sup>),where K is the number of users.…”
