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.

Self-synchronizing equalization techniques and systems

An antenna assembly, and an associated method, which exhibits a selected the antenna beam configuration. The direction of a primary lobe and of a null is selected to improve the signal-to-noise and signal-to-interference ratios of communication signals transmitted between two communication stations. When implemented to form a portion of a base station of a cellular communication system, the traffic capacity of the communication system can be increased and the infrastructure costs of the system can be reduced.
