Title: Experimental Validation of Spectrum Sensing Techniques Using Software-Defined Radio
Abstract: Software-defined radio (SDR) and cognitive radio (CR) system technologies provide added flexibility and offer improved efficiency to complete spectrum use. CR is obstreperous radio communication and networking technology. It is presently undergoing drastic development due to its potential to resolve many of the problems affecting existing systems. Sensing a spectrum is the crucial part of CR to sense the existence of primary users (PUs) or licensed user signals and exploit the spectrum holes. Hence, in this work, the testing of spectrum sensing technique for 16QAM and 64QAM transceivers on SDR testbed is carried out. Furthermore, this paper also addresses the practical signal detection and the impact of various filtering windowing methods on detected signals. Experimental tests are performed on SDR testbed, which employs universal software radio peripheral (USRP) N210 and GNU Radio as hardware and software platforms, respectively.
