Improved Downlink Channel Estimation in Time-Varying FDD Massive MIMO Systems
This establishes an analytical closed-form relationship between the optimal weights and the angular domain characteristics.
Exploiting Spatial and Temporal Correlations in Massive MIMO Systems Over Non-Stationary Aging Channels
Moreover, optimal pilot spacing remains unaffected by interference components such as path loss and the velocity of interference users.
Subspace-Informed Matrix Completion
To this end, we introduce a multi-weight nuclear norm optimization problem that concurrently promotes the low-rank property as well the information about the available subspaces.
Optimal Transmitter Design and Pilot Spacing in MIMO Non-Stationary Aging Channels
Previous studies have shown that multiple transmit and receive antennas can substantially enhance the sum-capacity of all users when the channel is known at the transmitter and in the case of uncorrelated transmit and receive antennas.
Towards Optimal Pilot Spacing and Power Control in Multi-Antenna Systems Operating Over Non-Stationary Rician Aging Channels
In particular, when the channel changes rapidly in time, channel aging degrades the performance in terms of spectral efficiency without proper pilot spacing and power control.
Blind Asynchronous Goal-Oriented Detection for Massive Connectivity
Resource allocation and multiple access schemes are instrumental for the success of communication networks, which facilitate seamless wireless connectivity among a growing population of uncoordinated and non-synchronized users.
Demixing Sines and Spikes Using Multiple Measurement Vectors
In this paper, we address the line spectral estimation problem with multiple measurement corrupted vectors.
