Eliminating Multipath Fading Improves Wireless Signal Reception

by George W. Webb, Igor Minin, & Oleg Minin SPIE Newsroom, accessed 7 Sep 2006 Dropped mobile phone connections, missing wireless data packets, and lost radio reception at traffic lights are all examples of the problems that can result from multipath fading (MPF). This phenomenon can also produce 'ghost' images in analog television and impair the accuracy of Global Positioning System receivers. Previous attempts to eliminate it have not been completely successful, so we developed a new technique that can drastically reduce MPF and improve signal power by a factor of more than 10³. Read more
