A Distributed Interference Alignment Approach Based on Grouping in Heterogeneous Network
IEEE Access, 2018 To effectively mitigate interference and improve the performance, we propose a grouping-based two-stage distributed interference alignment (GTDIA) scheme for a two-layered heterogeneous network (HetNet) in multi-user multiple-input-multiple-output (MIMO)

A Hybrid Approach to Spatial Multiplexing in Multiuser MIMO Downlinks
EURASIP Journal on Wireless Communications and Networking, 2004 In the downlink of a multiuser multiple-input multiple-output (MIMO) communication system, simultaneous transmission to several users requires joint optimization of the transmitted signals. Allowing all users to have multiple antennas adds an additional

Carrier Harmonic Modulation for Simultaneous Wireless Information and Power Transfer
IEEE Access, 2023 This paper presents the carrier harmonic modulation (CHM) for near-field data communication during wireless power transmission. The proposed CHM does not increase the coil dimension, and an additional data driver is not required.
