Résumé

In this paper, we analyze the bit error rate (BER) and the throughput of decode-and-forward (DF) relaying with imperfect channel estimation and in the presence of a jammer in the network. We consider a single DF relay scenario with orthogonal cooperative protocols and an active jammer during all the transmission phases attacking the relay and destination nodes in the network. In our analysis, we assume that the complex fading channel coefficients are estimated at the relay and destination levels with errors. We derive the error performance and the throughput of the network then we quantify the impact of channel estimation and the jamming power through the derivation of analytical performance expressions. Our simulation results confirm the accuracy of our analytical BER expression and quantify the performance degradation due to channel estimation and jamming signals. Also, simulation results show the performance of the throughput of the proposed system.
