Distributed downlink multi-cell processing requiring reduced-rate back-haul data exchange [PDF]

, 2011
Different-complexity Multi-Cell Processing (MCP) schemes employing Distributed Signal-to-Interference-Leakage-plus-Noise-Ratio (SILNR) precoding techniques are proposed, which require reduced back-haul data exchange in comparison to the conventional MCP ...

Modeling and Optimization of Frequency‐Doubled Radio‐Over‐Fiber Link Based on Deep Learning Technique

Advanced Photonics Research, Volume 7, Issue 3, March 2026.
This article proposes a deep learning (DL) approach for modeling and optimizing frequency‐doubled radio‐over‐fiber links. By collectively replacing traditional components with DL model, accurate system evaluation is achieved. Moreover, through an end‐to‐end architecture, performance optimization is accomplished.

Successive Block Diagonalization Precoding for Multi-User MIMO System

四川大学学报. 自然科学版, 2017
Block Diagonalization (BD) is a common linear precoding technique for the downlink of multi-user MIMO(MU-MIMO) systems. A drawback of conventional BD is that the effective channel gain for each data stream can be severely unbalanced when each user has ...

Multiuser precoding scheme and achievable rate analysis for massive MIMO system

EURASIP Journal on Wireless Communications and Networking, 2018
We analyze the downlink multiuser precoding of massive multiple input multiple output (MIMO) system, where the base station (BS) has ideal channel state information (CSI) and adopts three types of different linear precoding schemes, i.e., maximum ratio ...

Contribution of non‐orthogonal multiple access signalling to practical multibeam satellite deployments

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 73-88, January/February 2026.
The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.

Digital and analog hybrid precoding technology combined with V-BLAST in multi-user massive MIMO system

Dianxin kexue, 2016
In the massive MIMO system, the only full digital baseband precoding（FD-BP）scheme（such as full complexity zero forcing）requires the same number of radio frequency（RF）chains as the number of antenna elements, which leads to extreme high hardware cost, the
