The following is a list of patented innovations that I have developed, either independently or in collaboration with colleagues (as indicated). These inventions span signal detection and processing techniques for satellite communication receivers, together with routing and signalling mechanisms for satellite networks. Many of these technologies have been successfully deployed in the Thuraya and Iridium Low Earth Orbit (LEO) satellite systems, contributing to the realization of practical handheld satellite receivers
