Performance analysis of cooperative PDMA with AF relaying over …
AF relaying can avoid the above problems, since it does not decode any signal in the relay node. As shown in Figs. 3 and 4, the red curves standing for the optimum PA are not smooth when SNR is small. The changing of PA coefficients (see Fig. 1) leads to the red curve unsmooth. With respect to the green curves, they are smooth curves that are ...

Performance analysis of end-to-end SNR estimators for AF relaying
Many existing signal-to-noise ratio (SNR) estimators were designed and evaluated for conventional one-hop communications systems. However, for a relaying system, it is the end-to-end SNR that determines the system performance. In this paper, we will fill this gap by evaluating the performances of the existing SNR estimators in a dual-hop relaying system used …
