Partial Discharge Detection and Localization: Using Software-Defined Radio

Software Defined Radio Localization Using 802.11-style Communications

Indoor Navigation Using a Software Defined Radio

Time of Arrival (TOA) observations from local beacon signals can be used to augment and provide a back-up navigation source for GPS signals in a Software Defined Radio (SDR). The addition of inertial sensor inputs to the SDR offers the ability to track down to much lower power levels for both the GPS and TOA signals, effectively deal with multipath, and recover more quickly from signal outages....

Performance Analysis of AOA-based Localization with Software Defined Radio

In this paper, we investigate angle of arrival (AOA)-based estimation of a mobile station (MS)’s location by monitoring the AOA at multiple reference software defined radio (SDR) receivers. Each Universal software radio peripheral (USRP) device captures the AOA from the uplink transmission of a MS via MUltiple SIgnal Classification (MUSIC), which is one of super-resolution techniques to estimat...

Cognitive Radio Communications and Software Defined Radio

Increasing demands for high speed wireless access gave rise to new approach to radio communications and spectrum management – Cognitive Radio (CR). One of the key components of cognitive radio – dynamic spectrum access – shows a way to overcome the scarcity of one of the natural resources – radio frequency spectrum. The research in the domain of CR spans the wide area from information and signa...

Evaluating the Improvement of Partial Discharge Localization Accuracy Using Frequency Response Assurance Criterion

Partial Discharge (PD) is the most important source of insulation degradation in power transformers. In order to prevent catastrophic failures in transformers, PDs need to be located as soon as possible so that maintenance measures can be taken in time. Due to the structural complexity of windings, locating the PD source inside a transformer winding is not a simple task. In this paper, the effi...
