摘要

> >In this study, we propose a new Amplify-and-Forward (AF)amplification factor to improve the error performances of the current AFschemes and thus enhance the total capacity at the destination terminal. Theproposed scheme has two degrees of freedom,meaning that it contains two variable parameters that can simultaneously varythe amplification factor instead of one as in traditional variable-gain orsemi-blind relaying. The numerical results show that the proposed AF scheme outperformssome current ones with which it is compared in terms of average capacity andprobability of outage and thus brings AF relaying performances closer to thatof Decode-and Forward (DF) strategy which hitherto outperforms it. The resultsalso show that by increasing or decreasing the power share of the relay, theoptimal location of the relay is not only moved closer to or farther away fromthe destination, the total average capacity at that location is also correspondingly increased or decreased.
