RTL SDR THESIS

The localization result was within a 1. PD can degrade insulation and if left untreated can cause catastrophic insulation failure. Finally the comparison between the methods are stated with a complementary ROC plot. Civil engineering General Schools: The main advantages of SDR technology are that it is cost-effective and it is relatively immune against environmental noise. However, noise or interference also exists in the PD frequency band. Recently, an alternative method for PD detection and monitoring using wireless technology has become possible.

In this key factor is to find the spectrum holes then allocate those to the secondary user. 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. These result were validated using a high-end costly device, i. The spectrum allocation plays an important role in this. Rebecca Hill Date Deposited: Civil engineering General Schools: Generally, SDR devices demonstrate satisfactory results when compared to spectrum analyzers.

Here the analysis to find the white spaces are doneby collecting the real time signal with RTL-SDR and experimented on the platforms like matlab, Simulink, GNU radio and spectrum analyzer. Results of both systems were very satisfactory, although some results at the corners of the detection grid were not ser and the error was higher than 3 meters due to the fact that the RSS algorithm performs poorly at corners.

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. Spectrum scarcity occurs due dsr the rapid increase of the applications in wireless communication which results in the problem of bandwidth. 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.

School of Computing and Engineering. In this key factor is to find the spectrum holes then allocate those to the secondary user. These experiments were used to validate both systems for PD detection and localization in industrial environments.

There are two type users primary user PU and secondary user SU.

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. However, PD pulse monitoring and detection can save cost and life prior to plant failure. Recently, an alternative method for PD detection and monitoring using wireless technology has become possible.

Software Defined Radio has opened new opportunities to detect and monitor PD activity. 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 and removed.

Doctoral thesis, University of Huddersfield. This idea is to improve the efficiency of the spectrum utilization.

Finally the comparison between the methods are stated with a complementary ROC plot. The main advantages of SDR technology are that it is cost-effective and it is relatively immune against environmental noise.

Civil engineering General Schools: The spectrum allocation plays an important role in this. Rebecca Hill Date Deposited: Partial discharge PD occurs if a high voltage is applied to insulation that contains voids. PD can degrade insulation and if left untreated can cause catastrophic insulation failure.

Spectrum Sensing & Signal Identification Using RTL-SDR

For this purpose energy detection and cyclostationary detection two procedureare followed here, to determine spectrum holes. PD detection using SDR devices was conducted in the frequency domain. Cognitive radio is one of the modern techniques in the field of wireless wdr in order to solve the spectrum scarcity problem.

Hence in order to solve this problem cognitive radio follows the cognitive cycle in which spectrum sensing acts as a major procedure.

Generally, SDR devices demonstrate rrl results when compared to spectrum analyzers. 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.
