Dissertação de Mestrado em Comunicações Móveis apresentada à Escola Superior de Tecnologia do Instituto Politécnico de Castelo Branco.This document describes the work developed to implement a prototype able to operate in TVWS.Gives an overview about the digital switchover roadmap in Europe and surveys the trends in the TVWS market for different European countries. Describe the prototype specifications, also an overview about the TVWS prototype state of art. Describes the sensing techniques for PMSE detecting used in the prototype and the thresholds calculations.The metrics to evaluate the algorithms selected are presents. Also, describes the SDR systems, the chosen hardware, USRP and the features and limits, daughterboard selected. A resume about the software platform is present and the features that make this platform, Labview, the choice for integrating in the prototype Describes the development and implementation of the prototype and also include the test scenario conditions and results
