A Novel Algorithm to Report CSI in MIMO-Based Wireless Networks
Muhammad Karam Shehzad, Luca Rose, Mohamad Assaad
In wireless communication, accurate channel state information (CSI) is of pivotal importance. In practice, due to processing and feedback delays, estimated CSI can be outdated, whi…
Dealing with CSI Compression to Reduce Losses and Overhead: An Artificial Intelligence Approach
Muhammad Karam Shehzad, Luca Rose, Mohamad Assaad
Motivated by the issue of inaccurate channel state information (CSI) at the base station (BS), which is commonly due to feedback/processing delays and compression problems, in this…
Uplink Beam Management for Millimeter Wave Cellular MIMO Systems with Hybrid Beamforming
George C. Alexandropoulos, Ioanna Vinieratou, Mattia Rebato +2
Hybrid analog and digital BeamForming (HBF) is one of the enabling transceiver technologies for millimeter Wave (mmWave) Multiple Input Multiple Output (MIMO) systems. This technol…
Performance Assessment of MIMO Precoding on Realistic mmWave Channels
Mattia Rebato, Luca Rose, Michele Zorzi
In this paper, the performance of multi-user Multiple-Input Multiple-Output (MIMO) systems is evaluated in terms of SINR and capacity. We focus on the case of a downlink single-cel…
On the Nash Equilibria in Decentralized Parallel Interference Channels
Luca Rose, Samir M. Perlaza, Mérouane Debbah
In this paper, the 2-dimensional decentralized parallel interference channel (IC) with 2 transmitter-receiver pairs is modelled as a non-cooperative static game. Each transmitter i…
