Analysis of Extended Busy Tone Performance for Coexistence between WRAN and WLAN TVWS Networks
Karatalay, Onur; Erküçük, Serhat; Baykaş, Tunçer (IEEE, 2015)TV White Spaces indicate spectrum bands which were reserved for licensed terrestrial TV broadcasting and opened to unlicensed use under regulatory conditions. One important regulation which is common in all regulatory ... -
Busy tone based coexistence algorithm for WRAN and WLAN systems in TV white space
Karatalay, Onur; Erküçük, Serhat; Baykaş, Tunçer (Inst Engineering Technology-IET, 2018)TV White Space (TVWS) refers to frequency band reserved only for licensed terrestrial TV broadcasting and is opened to unlicensed use under regulatory conditions. While regulations protect licensed systems from interference ... -
