[CPl17] A Cognitive Radio System with Adaptive Decoding and Full-Duplex Relaying at the Secondary Receiver
Conférence Internationale avec comité de lecture :
International Conference on Communications (ICC), WT-07,
In this paper, we propose a new full-duplex relay-assisted
Cognitive Radio (CR) system model with an adaptive decoding
algorithm at the Secondary User (SU), 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 (AF) and
Decode-and-Forward (DF) relaying in the single-carrier case.
Then, we investigate the resource allocation problem for the
proposed system model with a DF 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.
