How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Currently working as a particle-physics firmware engineer for the ATLAS experiment at CERN and the DUNE experiment at Fermilab. In my previous job at University of Birmingham, SERENE group, my work primarily focused on understanding the effect of equatorial ionospheric scintillation on wideband UHF signals. UHF signals from geo-stationary satellites are analysed to estimate the ionospheric impulse response.

Six hundred hours of data from a receiver located at the Cape Verde Atmospheric Observatory at 15°N (dip latitude), has been used to explore the fading correlation of 300–360 MHz trans‐ionospheric signals from the MUOS satellite. Using these data, we have highlighted that the inter‐frequency correlation varies with the fading frequency; components...
Conference Paper
UHF SATCOM has a number of advantages over higher frequencies including better coverage in built up areas where the visibility of the satellite is prejudiced and better propagation through tree canopies. Typically, UHF satcom systems have low capacity being limited by simple 25 kHz narrow band waveforms. Wideband waveforms can overcome this capacit...
