Co-Existence between a Radar System and a Massive MIMO Wireless Cellular System

In this paper we consider the uplink of a massive MIMO communication system using 5G New Radio-compliant multiple access, which is to co-exist with a radar system using the same frequency band. We propose a system model taking into account the reverberation (clutter) produced ...

User-centric cell-free massive MIMO with interference cancellation and local ZF downlink precoding

In the user-centric (UC) cell-free Massive MINO architecture, a large number of distributed access points (APs) are deployed in a given area, each one serving the mobile stations (MSs) that are received with the largest power. This architecture has been shown to offer some adv...

Energy-Efficient Downlink Power Control in mmWave Cell-Free and User-Centric Massive MIMO

This paper considers cell-free and user-centric approaches for coverage improvement in wireless cellular systems operating at millimeter wave frequencies, and proposes downlink power control algorithms aimed at maximizing the global energy efficiency. To tackle the non-convexity of the problems, an&#x...
