A sparsity-aware cooperative protocol for cognitive radio networks with energy-harvesting primary user
(
IEEE
, 2015 , Conference Paper)
We consider a cognitive setting composed of multiple primary frequency bands each of which consists of a limited-battery energy-harvesting primary user and a secondary user. The primary user is equipped with a limited-capacity ...
Exploiting sparsity of relay-assisted cognitive radio networks
(
IEEE
, 2015 , Conference Paper)
We propose a novel protocol for secondary users based on compressive sensing principles. The secondary user assigned to one of the primary frequency bands is aided by a set of nearby secondary users, which we refer to as ...
