On the Role of Estimate-and-Forward With Time Sharing in Cooperative Communication
In this paper, we focus on the general relay channel. We investigate the application of the estimate-and-forward (EAF) relaying scheme to different scenarios. Specifically, we stud...

Interplay of spectral efficiency, power and doppler spectrum for reference-signal-assisted wireless communication
Expressions relating spectral efficiency, power, and Doppler spectrum, are derived for Rayleigh-faded wireless channels with Gaussian signal transmission. No side information on th...
