Abstract

This study presents an empirical investigation of the characteristics of the wireless signal received by an antenna that undergoes on-axis rotation in a line of sight indoor environment. The measured signal fading reaches up to 14 dB from the nominal position at certain antenna orientations due to polarization misalignment. Both the first order and second order statistics of the received signal are determined and compared to selected candidate distributions. The model is selected through goodness-of-fit statistics and by using the Akaike Information Criterion (AIC). Based on the AIC model ranking and the second order statistics, the Rice distribution best describes the channel fading due to on-axis rotation.

Acting Director

Dr. Marciano, Jr. Joined the DOST-ASTI in March 2016 as its Acting Director. He is a licensed Electronics Engineer who graduated with a degree in Bachelor of Science in Electrical Engineering from the University of the Philippines, Diliman and was conferred with Doctorate Degree in Electrical Engineering from the University of New South Wales.Under his leadership, the DOST-ASTI is reviving and ramping up its research on radio frequency (RF) electronics. This is done through various research projects, some of which are in collaboration with the UP-EEEI. Aside from form overseeing the operations of the DOST-ASTI, Dir. Marciano Jr. is currently engaged in several projects such as Communications Relay Buoys for the Communications Relay for CoCoMoNets, Development and Deployment of Advanced Spectrum Platform Network, Development of Software Defined Radio (SDR) based Satellite Telemetry and Telecommand System Simulator Projects, and Development of Extreme Weather Monitoring and Information Sharing System in the Philippines as Project Adviser, as well as the Project Leader of EPDC as Platform for Inclusive Innovation Program (EPIIC) and Synthetic Aperture Radar (SAR) and Automatic Identification System (AIS) for Innovative Terrestrial Monitoring and Maritime Surveillance.
