A Unified Convergence Analysis of Block Successive Minimization Methods for Nonsmooth Optimization
Meisam Razaviyayn, Mingyi Hong, Zhi-Quan Luo
The block coordinate descent (BCD) method is widely used for minimizing a continuous function f of several block variables. At each iteration of this method, a single block of vari…
Joint User Grouping and Linear Virtual Beamforming: Complexity, Algorithms and Approximation Bounds
Mingyi Hong, Zi Xu, Meisam Razaviyayn +1
In a wireless system with a large number of distributed nodes, the quality of communication can be greatly improved by pooling the nodes to perform joint transmission/reception. In…
Linear Transceiver Design for a MIMO Interfering Broadcast Channel Achieving Max-Min Fairness
Meisam Razaviyayn, Mingyi Hong, Zhi-Quan Luo
We consider the problem of linear transceiver design to achieve max-min fairness in a downlink MIMO multicell network. This problem can be formulated as maximizing the minimum rate…
