Performance Analysis of Massive MIMO Networks with Random Unitary Pilot Matrices
Rusdha Muharar, Jamie Evans
A common approach to obtain channel state information for massive MIMO networks is to use the same orthogonal training sequences in each cell. We call this the full-pilot reuse (FP…

Optimal Power Allocation and User Loading for Multiuser MISO Channels with Regularized Channel Inversion
Rusdha Muharar, Randa Zakhour, Jamie Evans
We consider a multiuser system where a single transmitter equipped with multiple antennas (the base station) communicates with multiple users each with a single antenna. Regularize…

Base Station Cooperation with Feedback Optimization: A Large System Analysis
Rusdha Muharar, Randa Zakhour, Jamie Evans
In this paper, we study feedback optimization problems that maximize the users' signal to interference plus noise ratio (SINR) in a two-cell MIMO broadcast channel. Assuming the us…
