Optimal Multiuser Zero Forcing with Per-Antenna Power Constraints for Network MIMO Coordination

EURASIP Journal on Wireless Communications and Networking, 2011
We consider a multicell multiple-input multiple-output (MIMO) coordinated downlink transmission, also known as network MIMO, under per-antenna power constraints.

Joint space-time Huffman limited feedback precoding for spatially and temporally correlated MIMO channels

Tongxin xuebao, 2013
For the MIMO channels with space correlation and time correlation, a novel joint space-time Huffman limited feedback precoding scheme was proposed which improves the system performance and reduces the amount of feedback.

Novel Leakage-Based Capacity Enhancement Scheme for Multi-User OAM Communications

IEEE Access
This paper explores a novel leakage-based capacity enhancement scheme in an orbital angular momentum (OAM) integrated multiuser MIMO system, where the leakage refers to the signal interference affecting other users.

Enhancing generalized receive spatial modulation by symbol-level precoding: Design guidelines with or without intelligent reflecting surfaces

Digital Communications and Networks
Existing Generalized Receive Spatial Modulation (GRSM) with Symbol-Level Precoding (SLP) forces the received signals (excluding noise) at unintended antennas to be zero, which restricts the generation of strong constructive interference to intended ...
