A new method makes the most efficient use of the scarce spectral bandwidth in a wireless discrete multitone spread spectrum communications system by updating the spectral and/or spatial spreading weights at a rate that is determined by the measured quality of the link. Low quality links require more...http://www.google.com/patents/US5923700?utm_source=gb-gplus-sharePatent US5923700 - Adaptive weight update method and system for a discrete multitone spread spectrum communications system
