Low priority communication (cognitive radio) over primary subchannels by applying a double power distribution
Medina Acosta, Gerardo Agni; Delgado Penin, José Antonio (2009)
Comunicació de congrés
Accés restringit per política de l'editorialIn this article, the proposal to establish a simultaneous cognitive radio communication based on a subdistribution of power made over discovered unselected subchannels identified by an initially optimal power allotment ... -
Método de detección de usuarios primarios utilizando una descomposición wavelet
Medina Acosta, Gerardo Agni; Delgado Penin, José Antonio (2009)
Comunicació de congrés
Accés obertThe sensing function is one of the most important features of cognitive radios since a reliable detection of available spectrum ensuring non-interference to licensed users is necessary to initiate a lower priority ... -
On the feasibility of a channel-dependent scheduling for the SC-FDMA in 3GPP-LTE (mobile environment) based on a prioritized-bifacet Hungarian method
Medina Acosta, Gerardo Agni; Delgado Penin, José Antonio (2011-08-19)
Article
Accés obertWe propose a methodology based on the prioritization and opportunistic reuse of the optimization algorithm known as Hungarian method for the feasible implementation of a channel-dependent scheduler in the long-term evolution ... -
On the reusage of primary radio resources through the exploitation of the spatiotemporal robustness of the MIMO transmissions
Medina Acosta, Gerardo Agni; Delgado Penin, José Antonio (2012-09-20)
Article
Accés obertThe spatiotemporal robustness of the MIMO transmissions is exploited aiming at inducing opportunistic secondary communications on the primary radio resources. The proposed model makes use of the smallest singular values ...
