چکیده
COGnitive radio systems for efficient sharing of TV white spaces in EUropean context (COGEU) is a threeyear Specific Target Research Project (STREP) supported by the EU 7th Framework Program which concluded in 2013. This paper presents the COGEU TV white space (TVWS) radio transceiver, a key demonstrator and deliverable of the project. The demonstrator consists of a Software Defined Radio (SDR) platform using the Iris software radio architecture for dynamic spectrum access using spectrally shaped, non-contiguous waveforms with intentionally embedded cyclostationary signatures for network rendezvous and coordination. A TVWS database is used for channel selection and a dedicated wireless microphone detector is integrated to ensure coexistence with Program Making and Special Events (PMSE) devices. An overview of the system architecture is provided and each of the algorithms used for microphone detection, transmit waveform shaping, network rendezvous and synchronization is described. Finally, the paper discusses the key challenges faced in the system implementation and details the solutions which were applied.

متن کاملTVWS policies to enable efficient spectrum sharing
The transition from analogue to the Digital Terrestrial Television (DTV) in Europe is planned to be completed by the end of the year 2012. The DTV spectrum allocation is such that there are a number of TV channels which cannot be used for additional high power broadcast transmitters due to mutual interference and hence are left unused within a given geographical location, i.e. the TV channels a...
