Analysis of spectral efficiency for OFDM cooperative cognitive networks with non‐linear relay

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 operates in...
