The transition from analogue to digital terrestrial
television (i.e. Digital Switchover - DSO) releases a significant
amount of valuable spectrum (i.e. Digital Dividend), in UHF
band. Digital Dividend will be available in the form of a “cleared
spectrum” of contiguous channels, as well as in the form of
“interleaved spectrum”, namely TV White Spaces (i.e. TVWS),
unused within given geographical locations, in order to avoid
causing interference to co-channel or adjacent channel DVB-T
transmitters. “Cleared spectrum” and TVWS provide an
opportunity to deploy Cognitive Radio (CR) networks, able to
operate in UHF band, by sharing the available spectrum with
other licensed systems. In this context, this paper elaborates on
the efficient sharing of TVWS by proposing a mobile TV network
with CR capabilities, based on DVB-H. The proposed network
operates as an unlicensed secondary system, accessing TVWS via
a spectrum broker, which is in charge of assigning the available
spectrum.
