“…USRP can be reconfigured (in runtime also) to desired specifications in host computer by using GNU Radio. GNU Radio is a free software development toolkit that offers the signal processing runtime and readily available more than 100 processing blocks to implement software radios employing low-cost external RF hardware (USRP) and allows real time SDR applications [1]. In GNU Radio, signal processing blocks are written in Python and those are connected using C++ and both languages are communicated by SWIG (Simplified Wrapper and Interface Generator) interface compiler.…”

“…Software Defined Radio (SDR) [1] is a term reinvented from software radio by Joseph Mitola in 1991, while recognizing the possibilities of re-configurability and re-programmability of radio systems. The idea behind software defined radio is to perform all signal processing functions with software instead of using dedicated circuitry.…”

“…Wireless Innovation Forum defined SDR as "radio in which some or all of the functions of the physical layer are defined by software", in other words SDR refers to technology which software modules are executed in real-time generic platforms microprocessors, digital signal processors or programmable logic circuitry to implement functions the signal to be transmitted generation (modulation) or detection of the received radio signal (demodulation) [6].…”

“…Initially, it was mainly used by amateur radio enthusiasts, but it later gained significant interest from wireless researchers, and today it has a large community of users and contributors [7]. The GNU Radio provides a development environment and note processing to implement SDR [6]. Several software algorithms include filters, channel codes, synchronization elements, equalizers, demodulators, decoders, and many other elements.…”

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.
