Analysis of spectral efficiency for OFDM cooperative cognitive networks with non‐linear relay
Abstract This paper analyzes the downlink achievable spectral efficiency of an orthogonal frequency‐division multiplexing (OFDM) cooperative cognitive network with a non‐linear relay. The analysis is carried out subject to the power amplifier's (PA) non‐linear effect on the relay node which ope...
