Abstract
A system for wireless communication between a base station 30 and one or more remote stations 32 and 34 wherein a desired signal has associated therewith an identifier tone (a SAT in the vernacular of the AMPS system) and wherein interfering signals may have associated therewith identifier tones at different frequencies. A superresolution technique is used in the system to process the received data and to determine the relative magnitudes of any identifier tones which may be present in the received data. In the disclosed embodiment, the superresolution technique utilized is a least square error process. The resulting estimates are used by the system to facilitate the communication function.
