Machine Learning-based Methods for Joint {Detection-Channel Estimation} in OFDM Systems

no code implementations8 Apr 2023 Wilson de Souza Junior, Taufik Abrao

In this work, two machine learning (ML)-based structures for joint detection-channel estimation in OFDM systems are proposed and extensively characterized.

OnRMap: An Online Radio Mapping Approach for Large Intelligent Surfaces

no code implementations6 Feb 2023 Herman L. Santos, Victor Croisfelt, Cristian J. Vaca-Rubio, Taufik Abrao, Petar Popovski

We introduce OnRMap, an online radio mapping (RMap) approach for the sensing and localization of active users (AUs), devices that are transmitting radio signals, and passive elements (PEs), elements that are in the environment and are illuminated by the AUs' radio signals.

Throughput and Latency in the Distributed Q-Learning Random Access mMTC Networks

no code implementations30 Oct 2021 Giovanni Maciel Ferreira Silva, Taufik Abrao

In mMTC mode, with thousands of devices trying to access network resources sporadically, the problem of random access (RA) and collisions between devices that select the same resources becomes crucial.

Randomized Kaczmarz Algorithm for Massive MIMO Systems with Channel Estimation and Spatial Correlation

1 code implementation8 Apr 2019 Victor Croisfelt Rodrigues, Jose Carlos Marinello Filho, Taufik Abrao

To exploit the benefits of massive multiple-input multiple-output (M-MIMO) technology in scenarios where base stations (BSs) need to be cheap and equipped with simple hardware, the computational complexity of classical signal processing schemes for spatial multiplexing of users shall be reduced.
