GFDM-Based Cooperative Relaying Networks with Wireless Energy Harvesting
(IEEE, 2019-10-21)
In this paper, the concept of wireless power transfer and wireless information transmission, which have recently received special attention for improving energy efficiency in wireless communication systems, are investigated. ...
What Role Do Intelligent Reflecting Surfaces Play in Multi-Antenna Non-Orthogonal Multiple Access?
(IEEE, 2020-10-28)
Massive multiple-input multiple-output (MIMO) and non-orthogonal multiple access (NOMA) are two key techniques for enabling massive connectivity in future wireless networks. A massive MIMO-NOMA system can deliver remarkable ...
Successive Sub-Array Activation for Massive MIMO-NOMA Networks
(IEEE, 2020-07-27)
In this paper, we propose a novel successive sub-array activation (SSAA) diversity scheme for a massive multiple-input multiple-output (MIMO) system in combination with non-orthogonal multiple access (NOMA). A single-cell ...
Achievable Sum Rate and Outage Capacity of GFDM Systems with MMSE Receivers
(IEEE, 2020-07-27)
This paper investigates the achievable sum rate and the outage capacity of generalized frequency division multiplexing systems (GFDMs) with minimum mean-square error (MMSE) receivers over frequency-selective Rayleigh fading ...
Massive MIMO-NOMA Networks with Imperfect SIC: Design and Fairness Enhancement
(IEEE, 2020-06-11)
This paper addresses multi-user multi-cluster massive multiple-input-multiple-output (MIMO) systems with non-orthogonal multiple access (NOMA). Assuming the downlink mode, and taking into consideration the impact of imperfect ...
