Abstract

This disclosure presents a receiver apparatus (10) and corresponding method that advantageously use ISI-canceling combining weights, as are generated for ISI suppression in the receiver's data signal combining operations, to suppress the effects of ISI from determinations of receiver frequency error. Such suppression yields more accurate receiver frequency error determination and, correspondingly, improved receiver frequency error compensation.
