A modified WMMSE algorithm that incorporates such factors is proposed. We evaluate the performance of the proposed WMMSE algorithm using a time division duplexing (TDD) LTE simulation platform, and show that our practice-oriented design can improve the system throughput by 3 ~ 30% in comparison ...
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...

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...
