Abstract:

In this paper, we propose a new full-duplex relay-assisted cognitive radio system model with an adaptive decoding algorithm at the secondary user, in order to maximize both primary and secondary achievable rates. We consider the uplink transmission and we compare the system's achievable rates obtained with both amplify-and-forward and decode-and-forward relaying in the single-carrier case. Then, we investigate the resource allocation problem for the proposed system model with a decode-and-forward relay node in the multi-carrier scheme. Simulation results show an important improvement of the achievable rates due to the relaying scheme and the adaptive decoding algorithm at the secondary receiver.
