RTL SDR THESIS

Partial discharge PD occurs if a high voltage is applied to insulation that contains voids. The spectrum allocation plays an important role in this. Doctoral thesis, University of Huddersfield. Recently, an alternative method for PD detection and monitoring using wireless technology has become possible. There are two type users primary user PU and secondary user SU.

Software Defined Radio has opened new opportunities to detect and monitor PD activity. These result were validated using a high-end costly device, i. These experiments were used to validate both systems for PD detection and localization in industrial environments. The localization result was within a 1. Selecting the appropriate SDR device depends on factors such as high sensitivity and selectivity. PD can degrade insulation and if left untreated can cause catastrophic insulation failure. Cognitive radio is one of the modern techniques in the field of wireless communication in order to solve the spectrum scarcity problem.

School of Computing and Engineering. Here the analysis to find the white spaces are doneby collecting the real time signal with RTL-SDR and experimented on the tthesis like matlab, Simulink, GNU radio and spectrum analyzer.

In addition, and for the purpose of evaluating the proposed scheme, more experiments were conducted using another system that is based on radiometric sensors which is WSN PD system.

The spectrum allocation plays an important role in this. Doctoral thesis, University of Huddersfield. School of Computing and Engineering Depositing User: PD is one of the predominant factors to be controlled to ensure reliability and undisrupted functions of power generators, motors, Gas Insulated Switchgear GIS and grid connected power distribution equipment.

Results of both systems were very satisfactory, although some results at the corners of the detection grid were not good and the error was higher than 3 meters due to the fact that the RSS algorithm performs poorly at corners.

The main advantages of SDR technology are that it is cost-effective and it is relatively immune against environmental noise. However, PD pulse monitoring and detection can save cost and life prior to plant failure. There are two type users primary user PU and secondary user Ryl.

Spectrum sensing largely focus on the effective and efficient utilization rt, the spectrum. Software Defined Radio has opened new opportunities to detect and monitor PD activity.

PD can degrade insulation and if left untreated can cause catastrophic insulation failure. Primary user those who are legally allotted to use the spectrum but for secondary user without license to use the spectrum avoiding interference can be done by spectrum sensing.

The localization result was within a 1. Cognitive radio is one of the modern techniques in the field of wireless communication in order to solve the spectrum scarcity problem.

AE Thesis: Wireless weather station signal reception using RTL-SDR system

Recently, an alternative method for PD detection and monitoring using wireless technology sdrr become possible. Generally, SDR devices demonstrate satisfactory results when compared to spectrum analyzers. Finally the comparison between the methods are stated with a complementary ROC plot. PDF Kb Abstract Cognitive radio is one of the modern techniques in the field of wireless communication in order to solve the spectrum scarcity problem.

For this purpose energy detection and cyclostationary detection gtl procedureare followed here, to determine spectrum holes. Civil engineering General Schools: However, noise or interference also exists in the PD frequency band.

Selecting the appropriate Wdr device depends on factors such as high sensitivity and selectivity. These result were validated using a high-end costly device, i. These experiments were used to validate both systems for PD detection and localization in industrial environments. Partial discharge PD occurs if a high voltage is applied to insulation that contains voids.

In this key factor is to find the spectrum holes then allocate those to the secondary user.

Spectrum Sensing & Signal Identification Using RTL-SDR – ethesis

This idea is to improve the efficiency of the spectrum utilization. PD detection using SDR devices was conducted in the frequency domain. These interferences are narrow band and mainly from FM, TV broadcasting and mobile telephony signals whose frequencies are well known, thus these interferences can be possibly processed tehsis removed.

Hence in order to solve this problem cognitive radio follows the cognitive cycle in which spectrum sensing acts as a major procedure. Rebecca Hill Date Deposited: Spectrum scarcity occurs due to the rapid increase of the applications in wireless communication which results in the problem of bandwidth.
