الملخص EN

For the OFDM-based Amplify-and-Forward cooperative system, a novel relay-superimposed pilot strategy is proposed, where the source pilot symbols are frequency division multiplexed to estimate the cascaded channel while relay pilot sequence is superimposed onto the top of the cooperative data stream for second-hop channel estimation.

This method avoids the loss of data rate for additional pilot subcarriers but results in the interference of unknown cooperative data.

To remove the interference of cooperative data during the estimation of second-hop channel, the Cooperative Interference Cancelation scheme assisted by cooperative data from direct link is proposed.

We derive the approximated lower bound for the MSE of second-hop channel estimation.

Simulation results are presented to validate the performance of the proposed schemes.
