To Relay or Not To Relay in Cognitive Radio Sensor Networks
(
IEEE
, 2014 , Article)
A recent investigation on MAC layer in cognitive radio networks proposed the primary packet relaying by the secondary node maintaining an extra queue used for this particular addable functionality. Nevertheless, relaying ...
On Channel Selection for Carrier Aggregation Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
In this paper, the problem of sub-channel selection for carrier aggregation (CA) systems is examined. CA enables the achievement of high data rate links via simultaneous transmissions over multiple component carriers. A ...
Distributed power allocation for multi-flow carrier aggregation in heterogeneous cognitive cellular networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
In this paper, we study distributed power allocation for multiflow carrier aggregation in cognitive cellular networks. Our approach differs from the conventional water filling (WF) algorithm since we deal with heterogeneous ...
Interference cancellation through interference alignment for downlink of cognitive cellular networks
(
Institution of Engineering and Technology
, 2015 , Article)
Interference cancellation through interference alignment (IA) at the downlink of cognitive cellular networks is proposed. IA helps the spatial resources to be shared among primary and secondary cells, and thus it can provide ...
