Distributed NOMA-Based Multi-Armed Bandit Approach for Channel Access in Cognitive Radio Networks

Usually, multiple secondary users (SUs) utilize the opportunistic spectrum access (OSA) in cognitive radio networks to communicate with the secondary base station (sBS). In uplink transmission, each SU can only select one channel from null null null {C}null null null primary channels to sense, access, and transmit data packets with the constraints of hardware and energy.
