In this paper, we consider a multi-user massive MIMO network with hybrid beamforming
architecture at the base station. The objective is to jointly perform user selection and design …

In massive MIMO systems, to partition users into groups and serve the groups separately
can significantly reduce the processing complexity. In the existing literature, user grouping is …

Massive multiple-input multiple-output (MIMO) systems are a key promising technology for
future broadband cellular networks. The propagation paths within massive MIMO radio …

We consider the problem of maximizing the minimum user achievable rate for downlink
massive MIMO multi-user systems. The max-min formulation promotes fairness such that all …

It is largely accepted that the innovative technology of large-scale multiantenna systems
(named Massive multiple input multiple output (MIMO) systems) will very probably be …

The implementation of multi-user massive multiple input multiple output (MIMO) systems
usually suffers from the increased complexity of system design. In such systems, the …

In this paper, the performance of massive multiuser multiple-input-multiple-output (MIMO)
