Abstract
In this paper, we suggest to optimize both power allocation coefficients, harvesting and sensing durations for cognitive radio networks using non orthogonal multiple access (CR-NOMA). In the first slot, secondary transmitter harvests energy from radio frequency signal received from node A. In the second slot, secondary transmitter sense the channel to check if primary user is active or not. When primary user is idle, secondary transmitter transmits data to N NOMA users in the third slot. We derive and optimize the total throughput for Rayleigh channels.
