“…In other visionary fields, SDR experiments have provided encouraging results that motivate to continue the investigations. Potential applications are being found in areas as diverse as prototypes development [60], microscopic investigations of the strength of the magnetic resonance [61], aviation tests [62], evaluation of multi-path communications [40], broadcast transmissions in multi-media mobile environments [63], cooperative wireless networks diversity [64], crossings prototypes between wireless networks layer, quantum optical communications and particularly in cognitive radio research [65][66][67][68].…”

<p align="justify">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.</p>

Software Defined Radio (SDR) is a flexible architecture which can be configured to adapt various wireless standards, waveforms, frequency bands, bandwidths, and modes of operations. This paper presents a detailed survey of the existing hardware and software platform for SDRs. It also presents prototype system for designing and testing of software defined radios in MATLAB/Simulink and briefly discusses the salient functions of the prototype system for Cognitive Radio (CR). A prototype system for wireless personal area network is built and interfaced with a Universal Software Radio Peripheral-2 (USRP2) main-board and RFX2400 daughter board from EttusResearch LLC. The philosophy behind the prototype is to do all waveform-specific processing such as channel coding, modulation, filtering etc. on a host (PC) and general purpose high-speed operations like digital up and down conversion, decimation and interpolation etc. inside FPGA on an USRP2. MATLAB has a rich family of toolboxes that allows building software-defined and cognitive radio to explore various spectrum sensing, prediction and management techniques.

“…The SDR concept paved the way for Cognitive Radios, where the electromagnetic environment is continuously sensed, in order to find empty slots and operate accordingly, dynamically varying the modulation and occupied frequencies. That enables a more efficient and lean use of the spectrum [3], [4]. Spectrum monitoring is, therefore, a preliminary core function for enabling a Cognitive Radio.…”

A low-cost spectrum analyzer is presented, based on a commercial software defined radio and an open-source application package. Fundamentals regarding the receiving operation and its sensitivity are presented, along with measurements, of two 8 and 12-bits software defined radio models. An application, run within GNU Radio, is presented, deployed to overcome the hardware analog-to-digital converter limitation to monitor wide bandwidths. Results are shown for two different frequency ranges, 200 MHz bandwidth.
