SDR-WBFM Receiver as an alternative to replace equipment in FM extended

Abstract

Abstract-A presidential decree in Brazil authorizing the migration of AM broadcast to FM. To accommodate these stations, the FM band will receive the frequencies of the channels 5 and 6 of analog TV, which became known as "FM extended". One of the barriers found in migration is the acquisition of equipment by the users, as the current equipment does not have the expected range in FM extended. To mitigate this problem, the implementation of an FM receiver using the Software Defined Radio (SDR) for its flexibility is proposed. The receiver was developed in GNU Radio environment, with a simple programming was possible to create a low-cost receiver and can serve as an alternative to users for receiving the new band.
