Efficient Constant Envelope Precoding for Massive MU-MIMO Downlink via Majorization-Minimization Method [PDF]
The practical implementation of massive multi-user multi-input–multi-output (MU-MIMO) downlink communication systems power amplifiers that are energy efficient; otherwise, the power consumption of the base station (BS) will be prohibitive.

Constellation Precoded Beamforming [PDF]
We present and analyze the performance of constellation precoded beamforming. This multi-input multi-output transmission technique is based on the singular value decomposition of a channel matrix. In this work, the beamformer is precoded to improve its diversity performance.

Hybrid Precoding for mmWave MIMO Systems With Overlapped Subarray Architecture
Traditional precoding is incompatible with millimetre wave (mmWave) multiple input multiple output (MIMO) systems due to hardware costs and power consumption.

Precoder Distribution and Adaptive Codebook in Wideband Precoding [PDF]
Based on wideband precoding (WBP) in the multiple-input multiple-output orthogonal frequency division multiplexing system, an adaptive nonuniform codebook is presented in this paper. The relationship between the precoder distribution and spatial correlation is analyzed at first.

Low-Complexity Hybrid Precoding for Subarray Architecture mmWave MIMO Systems
Hybrid precoding for millimeter wave (mmWave) multiple-input multiple-output (MIMO) systems has attracted much attention in recent years for subarray architecture compared to array architecture because of its low cost and low power consumption.

A Unified Framework for Precoding and Pilot Design for FDD Symbol-Level Precoding [PDF]
Large-scale antenna array techniques are key enablers for modern wireless communication systems. Channel state information (CSI) is indispensable for large-scale multi-antenna systems, but is challenging to obtain. To tackle this issue, in this paper we propose a unified precoding and pilot design frame-work, that allows minimal and precoding-sensitive
