RTL SDR THESIS

RTL SDR THESIS

The main advantages of SDR technology are that it is cost-effective and it is relatively immune against environmental noise. There are two type users primary user PU and secondary user SU. Doctoral thesis, University of Huddersfield. The spectrum allocation plays an important role in this. 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. Recently, an alternative method for PD detection and monitoring using wireless technology has become possible. Partial discharge PD occurs if a high voltage is applied to insulation that contains voids. 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. For this purpose energy detection and cyclostationary detection two procedure , are followed here, to determine spectrum holes. 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. 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.

Hence in order to solve this problem cognitive radio follows the cognitive cycle in which spectrum sensing acts as a major procedure. Cognitive radio is one of the modern techniques in the field of wireless communication in order to solve the spectrum scarcity problem.

The spectrum allocation plays an important role in this. Civil engineering General Schools: The localization result was within a 1. In this key factor is to find the spectrum holes then allocate those to the secondary user. 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.

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.

Spectrum Sensing & Signal Identification Using RTL-SDR

There are two type users primary user PU and secondary user SU. Spectrum sensing largely focus on the effective and efficient utilization of the rgl. 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.

This idea is to improve the efficiency of the spectrum utilization. School of Computing and Engineering. Selecting the appropriate SDR device depends on factors such as high sensitivity and selectivity. 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.

These experiments were used xdr validate both systems for PD detection and localization in industrial environments. 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 thewis secondary user without license to use the spectrum avoiding interference thwsis be done by spectrum sensing.

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. Doctoral thesis, University of Huddersfield.

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.

PD detection using SDR devices was conducted in the frequency domain. Partial discharge PD occurs if a high voltage is applied ryl insulation that contains voids. School of Computing and Engineering Depositing User: Generally, SDR devices demonstrate satisfactory results when compared to spectrum analyzers. Ttl, PD pulse monitoring and detection can save cost and life rtk to plant failure.

For this purpose energy detection and cyclostationary detection two procedureare followed here, to determine spectrum holes.

These result were validated using a high-end costly device, i. However, noise or interference also exists in the PD frequency band.

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.
