“…The system is helpful in detection and monitoring signals at laboratory environment for various R&D applications. The overall cost of the system is very less as compared to other SDR systems [6], [7]. Few signal processing blocks used in the model in order to keep the design simple for testing purposes.…”

Low cost signal detection and monitoring system is designed in this paper. Wireless Transmission Monitoring is required by security agencies in order to check transmissions taking place in a particular area. In this paper Wireless Transmission Monitoring System is implemented using GNU Radio and RTL-SDR device. The implemented system is capable to monitor signals of GSM Transmission, Commercial FM Broadcast; the system is developed using Software Defined Radio based RTL-SDR hardware. Monitoring System can also be extended as a signal receiver by making certain additions in the designed model. In this paper Multiple RTL-SDR device based signal detection system is also designed. FM signals were successfully detected by the system in laboratory environment.

“…One of the basic functions of the cognitive radio is spectrum sensing which have in the past been carried out with spectrum analysers by researchers. However, these spectrum analysers are expensive compared to the softwaredefined radios (SDRs) and the results of these designs (both the spectrum analysers and softwaredefined radios (SDRS)) only show little difference in measured spectrum occupancy (Fanan, et al, 2015). Section 1.1 reviews existing sensing algorithms and techniques used by researchers in cognitive radio design.…”

Cognitive radio has received considerable amount of attention as a promising technique to provide dynamic spectrum allocation. Spectrum sensing is one of the basic functions in the cognitive radio and is crucial to all other functions. Software- defined radios (SDRs) are considered due to its very high flexibility and have become a common platform for CR implementation replacing expensive spectrum analysers. The most popular among various SDR platforms is the universal software-defined radio peripheral (USRP). This paper presents a real-time swept spectrum sensing solution based on USRP B210. It also presents a detailed explanation of the concept of energy detection and the methodology for wide-band sensing. Finally, the performance of the proposed sensing solution is analysed through FFT graphs and spectrogram plot taken for 8 hours. The results showed that the proposed sensing solution was capable of achieving high resolution in the frequency domain of the wide band measured which implies that wide bands with heterogenous signals like the ISM band can be accurately resolved and analysed.

“…To develop a prototype with the characteristics mentioned above, one of the alternatives is with the use of Software-Defined Radios (SDR) technology. Currently, SDR [1] devices in conjunction with a development software allow researchers to collect information such as signal level. Initially, the values collected by the SDR devices do not have the necessary reliability for decision making, requiring a calibration of the collected values in relation to a reference value.…”
