Flexible Continuous Aperture Arrays
Kuranage Roche Rayan Ranasinghe, Zhaolin Wang, Giuseppe Thadeu Freitas de Abreu +1
A novel electromagnetic (EM) structure termed flexible continuous aperture array (FCAPA) is proposed, which incorporates inherent surface flexibility into typical continuous apertu…
Precoding for Uplink RIS-Assisted Cell-Free MIMO-OFDM Systems with Hardware Impairments
Navid Reyhanian, Reza Ghaderi Zefreh, Parisa Ramezani +1
This paper studies a reconfigurable intelligent surface (RIS)-assisted cell-free massive multiple-input multiple-output (CF-mMIMO) system with multiple RISs. Joint design of transm…
Joint Spatial and Spectral Hybrid Precoding for Multi-User MIMO-OFDM Systems
Navid Reyhanian, Reza Ghaderi Zefreh, Parisa Ramezani +1
Millimeter wave (mmWave) multiple-input multiple-output (MIMO) systems operate over wide bandwidths and frequency-selective channels, making orthogonal frequency-division multiplex…
Multi-Task Over-the-Air Federated Learning in Cell-Free Massive MIMO Systems
Chen Chen, Emil Björnson, Carlo Fischione
Wireless devices are expected to provide a wide range of AI services in 6G networks. The increasing computing capabilities of wireless devices and the surge of wireless data motiva…
