ABSTRACT:
Methods and systems for processing received radio signals are described wherein the finite alphabet quality of digital transmissions is utilized to improve performance. Nonsynchronous sampling of received signals introduces intersymbol interference which is compensated for by these methods and systems. Different types of signal modulation, and their impact on this type of intersymbol interference are discussed. A robust diversity combining technique, usable in conjunction with antenna arrays is developed.
