Optimal Interference Exploitation Waveform Design with Relaxed Block-Level Power Constraints
Xiao Tong, Lei Lei, Ang Li +2
This paper investigates constructive interference (CI)-based waveform design for phase shift keying and quadrature amplitude modulation symbols under relaxed block-level power cons…
MU-MIMO Symbol-Level Precoding for QAM Constellations with Maximum Likelihood Receivers
X. Tong, A. Li, L. Lei +4
In this paper, we investigate symbol-level precoding (SLP) and efficient decoding techniques for downlink transmission, where we focus on scenarios where the base station (BS) tran…
Symbol-Level Precoding for MU-MIMO System with RIRC Receiver
Xiao Tong, Ang Li, Lei Lei +2
Consider a multiuser multiple-input multiple-output (MU-MIMO) downlink system in which the base station (BS) sends multiple data streams to multi-antenna users via symbol-level pre…
NOMA Made Practical: Removing the Receive SIC Processing through Interference Exploitation
Abdelhamid Salem, Xiao Tong, Ang Li +1
Non-orthogonal multiple access (NOMA) is a powerful transmission technique that enhances the spectral efficiency of communication links, and is being investigated for 5G standards…
