MACHADO-FERNANDEZ, José Raúl. Software Defined Radio: Basic Principles and Applications. Rev. Fac. ing. [online]. 2015, vol.24, n.38, pp.79-96. ISSN 0121-1129.

The author makes a review of the SDR (Software Defined Radio) technology, including hardware schemes and application fields. A low performance device is presented and several tests are executed with it using free software. With the acquired experience, SDR employment opportunities are identified for low-cost solutions that can solve significant problems. In addition, a list of the most important frameworks related to the technology developed in the last years is offered, recommending the use of three of them.

Keywords : Software Defined Radio (SDR); radiofrequencies receiver; radiofrequencies transmitter; radio development frameworks; superheterodyne receiver; SDR hardware devices; SDR-Sharp; RTLSDR-Scanner.
