Optical signal processing of interference and fading effects inhigh bit rate mobile communication

摘要

High bit rate and high speed mobile radio communications usingmicrowaves and millimeter waves are very attractive for wireless megaand giga bits LAN and video transmissions. Radio interferences due tomulti-propagation paths and multiple scattering by street buildings andnatural structures of hills and trees are very important problems forhigh bit rate mobile radio communications. Real time high speed signalprocessing for delayed fading noises may be required. Optical signalprocessing using optical and radio interactions are most useful toaccomplish real time high speed signal processing. Fundamentalproperties and applications of optical signal processors using opticalactive waveguide devices are shown for high bit-rate mobilecommunications
