A Radio Spectrum Measurement Platform for Spectrum Surveying in Cognitive Radio

Abstract: Abstract. This paper presents a sophisticated radio spectrum measurement platform specifically envisaged and designed for spectrum occupancy surveys in the context of Dynamic Spectrum Access/Cognitive Radio (DSA/CR). The presented tool is a very flexible computer-controlled radio measurement system, which has successfully been used in extensive spectrum measurement campaigns and empirical studies in the context of the DSA/CR technology. An exhaustive and in-depth description of the developed measurement platfo… Show more

“…The captured power samples are compared to a decision threshold, following an energy detection method [42], in order to extract binary busy/idle channel occupancy patterns. A detailed description of the measurement platform design and configuration and associated methodological aspects can be found in [43], [44].…”

“…To further identify the channels that interfere with adjacent channels and cause an error when evaluating the spectrum occupancy, we use the proposed criteria in Section 4.5.2 and the duty cycle estimated in Section 5.2. Based on the obtained (D P c and D G c ), we found 16 channels ( Channel 2,4,6,11,16,30,32,34,35,37,60,61,63,69, 79 and 81) that interfere their adjacent channels in both guardbands and passbands. They are previously classified as the abnormally used channels, while other 12 abnormally used channels are inobvious interference source channels because the observable power levels in the guardband of their adjacent channels are not certainly from them.…”

“…These systems enhance the spectrum sensing decision process of CR, but only the high SNR signal is validated. As an example of the high-performance spectrum analyzer, References [35,36] captures the low SNR signal by enabling computer software to function on Virtual Instrument Software Architecture (VISA) and Standard Commands for Programmable Instruments (SCPI) softwares so that they realize the evaluation of the spectrum usage in a full frequency band.…”

“…In addition to Fig. 1 Example of a balanced spectrum measurement platform [29]. these filters, a band-stop filter may be necessary to remove overloading FM signals that may lead to problems of saturation or dynamic range (especially when performing measurements in urban environments, where high-power FM broadcast stations may be near the measurement location).…”
