Davis receives patent for optical wireless communication


ISR-affiliated Professor Christopher Davis (ECE) was issued U.S. Patent No. 7,106,971 on Sept. 12 for "System and Method for Optical Wireless Communication." The invention facilitates optical wireless communication with fading resistance. A delayed diversity approach reduces fading significantly by sending data in a set of light signals which each have a different polarization and/or a different wavelength. Each light signal is carried over a different, uncorrelated "channel" through the atmosphere. The receiver adjusts and combines the signals into a single signal. | ISR patents page |
