Implement of multiple access technique by wireless power transfer and relaying network

In this paper, we investigate non-orthogonal multiple access (NOMA) network relying on wireless power transfer to prolong lifetime. The base station (BS) sends common signals the relay with two functions (energy harvesting (EH) and signal processing) further serve NOMA users in downlink. Performance gap exists since different allocation factor assigned from splitting protocol adopted at such employs both amplify-and-forward (AF) decode-and-forward schemes. To provide performance metrics, prove formulas of outage probability which is a function transmit noise ratio. Simulation results indicate specific parameters adjust system user considered EH-NOMA system. This finding important recommendation design shows particular required target rates.
