Minimizing Energy Consumption in MU-MIMO via Antenna Muting by Neural Networks with Asymmetric Loss

no code implementations8 Jun 2023 Nuwanthika Rajapaksha, Jafar Mohammadi, Stefan Wesemann, Thorsten Wild, Nandana Rajatheva

In this paper, we consider the downlink transmission of an MU-MIMO network where TAM is formulated to minimize the number of active antennas in the BS while guaranteeing the per-user throughput requirements.

Blind Coherent Preamble Detection via Neural Networks

no code implementations30 Sep 2021 Jafar Mohammadi, Gerhard Schreiber, Thorsten Wild, Yejian Chen

Instead, we propose to use NN only for \textit{blind} coherent combining of the signals in the detector to compensate for the channel effect, thus maximize the signal to noise ratio.

Interference Distribution Prediction for Link Adaptation in Ultra-Reliable Low-Latency Communications

no code implementations1 Jul 2020 Alessandro Brighente, Jafar Mohammadi, Paolo Baracca

Motivated by the fact that most of the URLLC use cases with most extreme latency and reliability requirements are characterized by semi-deterministic traffic, we propose to exploit the time correlation of the interference to compute useful statistics needed to predict the interference power in the next transmission.

Distributed Differentially Private Computation of Functions with Correlated Noise

2 code implementations22 Apr 2019 Hafiz Imtiaz, Jafar Mohammadi, Anand D. Sarwate

CAPE can be used in conjunction with the functional mechanism for statistical and machine learning optimization problems.
