加权最⼩均⽅误差（weightedminimummeansquareerror,WMMSE ）算法加权最⼩均⽅误差（weighted minimum mean square error, WMMSE ）算法[1]⼀、问题描述 考虑MIMO系统中的下⾏链路，基站发射天线数为，⽤户数为，每个⽤户的接收天线数为。⽤户的MIMO信道记为，则其在采样时间时的接受信号可以表⽰为...
The weighted minimum mean-square error (WMMSE) algorithm is a popular approach for WSR maximization. However, its computational complexity is cubic in the number of base station (BS) antennas, which is unaffordable when the BS is equipped with a large antenna array. In this paper, we consider...

Based on alternation direction method of multipliers(ADMM), the proposed algorithm can solve the optimal precoder in a distributed manner. With asynchronous information exchange mechanism considered, the convergence rate of our algorithm can be accelerated further. Numerical results demonstrate the increase...
solution, we\npropose a scheme based on the minimization of the weighted mean square error,\nwhich achieves performance reasonably close to the optimum and allows to\nclearly outperforms a conventional orthogonal multiple access approach.\nNumerical results assess the effectiveness of our algorithm.Fab...
