Performance of Multibeam Satellite Systems with Tomlinson-Harashima Precoding [PDF]

, 2009
A multibeam satellite system can be modelled as a multiple-input multiple-output (MIMO) system with an interbeam interference matrix that is derived from the positions of the users in the different beams.

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.

A low complexity optimization algorithm for zero-forcing precoding under per-antenna power constraints

, 2015
Zero-forcing beamforming (ZFBF) is a popular pre-coding scheme for MIMO systems. Most of the studies in the literature are under total power constraints. However, the perantenna power constraints (PAPC) are more realistic.

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.
