Boosting Spectral Efficiency with Data-Carrying Reference Signals on the Grassmann Manifold
In wireless networks, frequent reference signal transmission for accurate channel reconstruction may reduce spectral efficiency.
Grant-Free Access via Bilinear Inference for Cell-Free MIMO with Low-Coherent Pilots
We propose a novel joint activity, channel, and data estimation (JACDE) scheme for cell-free multiple-input multiple-output (MIMO) systems compliant with fifth-generation (5G) new radio (NR) orthogonal frequency-division multiplexing (OFDM) signaling.
Full-Duplex MIMO Systems with Hardware Limitations and Imperfect Channel Estimation
We consider a bidirectional in-band full-duplex (FD) multiple-input multiple-output (MIMO) system subject to imperfect channel state information (CSI), hardware distortion, and limited analog cancellation capability as well as the self-interference (SI) power requirement at the receiver analog domain so as to avoid the saturation of low noise amplifier (LNA).
Discrete-Aware Matrix Completion via Proximal Gradient
We present a novel algorithm for the completion of low-rank matrices whose entries are limited to a finite discrete alphabet.
Robust Symbol Detection in Overloaded NOMA Systems
Simulation results show that the proposed art significantly outperforms both classic receivers, such as the LMMSE, and recent CS-based alternatives, such as the SOAV and the SCSR detectors.
