On the performance of spectrum sensing based on GLR for full-duplex cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In cognitive radio networks, secondary users (SUs) utilize the unused spectrum slots in the assigned band for the primary users (PUs). Conventional cognitive radio networks operate in half-duplex (HD) mode. Recently, ...
Optimal collaborative energy harvesting spectrum sensing with limited time resource
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
We study a collaborative spectrum sensing (CSS) problem with limited time and energy resources in cognitive radio (CR) network. Time duration of sensing and data transmission, if the spectrum is identified as vacant, are ...
