On Energy Harvesting in Hybrid Massive MIMO Cooperative NOMA in a Multiuser Cell

Abstract

In this paper we have considered an energy harvesting hybrid massive MIMO cooperative NOMA scheme using hybrid SWIPT protocol in a multiuser cell. Semi-orthogonal User Selection- Receive Antenna Selection Algorithm (SUS-RAS) algorithm is used to create the zero-forcing user set and select the receive antennas of each user for signal reception. Then User Matching-Receive Antenna Selection Algorithm (UM-RAS) is used to group the matched users with the users in the zero-forcing user set and also to select the antennas for signal reception. MaxMax algorithm is used to select the antenna pair for relaying between the users in each cluster. Finally, some numerical studies are shown that demonstrate the advantage of massive MIMO concept, cooperative NOMA along with hybrid SWIPT protocol for energy harvesting.
