Millimeter-Wave NOMA with Hybrid Beamforming

2019 IEEE International Conference on Communications Workshops (ICC Workshops), 2019
This paper investigates the application of nonorthogonal multiple access in millimeter-Wave communications (mmWave-NOMA) with hybrid beamforming. A user grouping algorithm is first proposed according to channel gains and channel correlations. Whereafter, a joint hybrid beamforming and power allocation problem is formulated to maximize the achievable ...

Rate Splitting-Based Hybrid Beamforming for Multi-User Downlink Cellular Networks

IEEE Transactions on Communications
We study a new rate splitting (RS)-based hybrid beamforming scheme for multi-user downlink cellular networks in which the base station having a hybrid beamforming structure serves multiple users each having conventional multiple antennas. To maximize the

Hybrid beamforming for massive MIMO

2018
Deployed with a large number of antenna elements, massive multiple-input-multiple-output (MIMO) systems will be an important component of next generation wireless systems, because they provide tremendous increase of spectral efficiency. However, two major challenges hinder the implementation of massive MIMO in a practical system.

New Predistorter Architecture for Hybrid Beamforming Transmitter

2020 IEEE 92nd Vehicular Technology Conference (VTC2020-Fall), 2020
In this paper, we propose a novel subarray digital predistorter (DPD) with timely shared feedback for hybrid beamforming transmitters. This enables a set of power amplifiers (PAs) to be linearized with a single DPD. The output signal in the proposed DPD comprises the weighted combination of the inverse functions of the individual PAs from an array ...
