Cooperative NOMA with Antenna Selection Schemes
2019 27th Signal Processing and Communications Applications Conference (SIU), 2019 In this paper, we study the performance of nonorthogonal multiple access (NOMA) based on antenna selection schemes in dual hop amplify-and-forward relay network over Rayleigh fading channels. In the network, base station and mobile users are equipped with multiple antennas, whereas the relay has multiple receive antennas and single transmit antenna ...

Low-Complexity Transmit Antenna Selection and Beamforming for Large-Scale MIMO Communications
International Journal of Antennas and Propagation, 2014 Transmit antenna selection plays an important role in large-scale multiple-input multiple-output (MIMO) communications, but optimal large-scale MIMO antenna selection is a technical challenge. Exhaustive search is often employed in antenna selection, but

Journal of Computer Networks and Communications, 2018 In massive multiple-input multiple-output (M-MIMO) systems, a large number of antennas increase system complexity as well as the cost of hardware. In this paper, we propose an M-MIMO-OFDM model using per-subcarrier antenna selection and bulk antenna ...

Optimal Antenna Selection Designs for Coupled MIMO Systems
International Journal of Antennas and Propagation, 2012 We consider the impact of antenna mutual coupling on receive antenna selection systems. Prior work on selection with mutual coupling has not considered the effects of the inactive (i.e., unselected) antenna terminations and spatial noise correlation.

A Fast Adaptive Receive Antenna Selection Method in MIMO System
International Journal of Antennas and Propagation, 2013 Antenna selection has been regarded as an effective method to acquire the diversity benefits of multiple antennas while potentially reduce hardware costs. This paper focuses on receive antenna selection. According to the proportion between the numbers of
