Latest Patents

One of Ali Abdallah's latest patents is titled "Receiver design for Doppler positioning with low earth orbit satellites and differential carrier phase measurements." This patent outlines system and device configurations for determining position based on low Earth orbit (LEO) satellite signals. The framework includes performing Doppler frequency measurement for received quadrature phase shift keying (QPSK) signals. It also incorporates channel tracking operations to determine Doppler shift measurements and a navigation filter operation to assess clock drift based on each measurement. Additionally, it provides methods for determining the position of a device using LEO satellite signal sources while canceling the effects of ionospheric and tropospheric delays.

Another notable patent is "Indoor localization with LTE carrier phase measurements and synthetic aperture antenna array." This innovation presents a spatial approach to mitigate multipath error for an indoor pedestrian localization system using broadband communication signals, such as LTE carrier phase measurements. The motion of a receiver is utilized to synthesize an antenna array from time-separated elements, allowing for synthetic aperture navigation that suppresses multipath error based on the direction-of-arrival (DOA) of incoming LTE signals.
