Resumo

Recently, a simple and efficient policy was proposed to allocate power among an arbitrary number of lossy-forward relays operating over Rayleigh fading channels. It is arguable, however, that a policy used in one fading scenario will equally perform in another. Motivated by this, we design a new power allocation policy that extends the referred one to operate in an arbitrary fading scenario. The proposed allocation is written in terms of the channel's diversity order, known or derivable for any of the existing fading models. We illustrate our method by specializing it to the Nakagami-m scenario. The new policy proves particularly advantageous whenever the relays are unequally apart from the destination, a realistic circumstance. (AU)
