Offline Reinforcement Learning and Sequence Modeling for Downlink Link Adaptation
Samuele Peri, Alessio Russo, Gabor Fodor +1
Link adaptation (LA) is an essential function in modern wireless communication systems that dynamically adjusts the transmission rate of a communication link to match time- and fre…
Near-Field ISAC in 6G: Addressing Phase Nonlinearity via Lifted Super-Resolution
Sajad Daei, Amirreza Zamani, Saikat Chatterjee +2
Integrated sensing and communications (ISAC) is a promising component of 6G networks, fusing communication and radar technologies to facilitate new services. Additionally, the use…
Improved Downlink Channel Estimation in Time-Varying FDD Massive MIMO Systems
Sajad Daei, Mikael Skoglund, Gabor Fodor
In this work, we address the challenge of accurately obtaining channel state information at the transmitter (CSIT) for frequency division duplexing (FDD) multiple input multiple ou…
Optimal Transmitter Design and Pilot Spacing in MIMO Non-Stationary Aging Channels
Sajad Daei, Gabor Fodor, Mikael Skoglund
This work considers an uplink wireless communication system where multiple users with multiple antennas transmit data frames over dynamic channels. Previous studies have shown that…
Subspace-Informed Matrix Completion
Hamideh. Sadat Fazael Ardakani, Sajad Daei, Arash Amini +2
In this work, we consider the matrix completion problem, where the objective is to reconstruct a low-rank matrix from a few observed entries. A commonly employed approach involves…
Timely and Painless Breakups: Off-the-grid Blind Message Recovery and Users' Demixing
Sajad Daei, Saeed Razavikia, Mikael Skoglund +2
In the near future, the Internet of Things will interconnect billions of devices, forming a vast network where users sporadically transmit short messages through multi-path wireles…
Exploiting Spatial and Temporal Correlations in Massive MIMO Systems Operating Over Non-Stationary Aging Channels
Sajad Daei, Gabor Fodor, Mikael Skoglund
This work investigates a multi-user, multi-antenna uplink wireless system, in which multiple users transmit signals to a base station. Prior research has explored the potential for…
Towards Optimal Pilot Spacing and Power Control in Multi-Antenna Systems Operating Over Non-Stationary Rician Aging Channels
Sajad Daei, Gabor Fodor, Mikael Skoglund +1
Several previous works have addressed the inherent trade-off between allocating resources in the power and time domains to pilot and data signals in multiple input multiple output…
