Abstract
Aspects of a method and system for a flexible automatic frequency control (AFC) design supporting transmit diversity are presented. Aspects of the system may include one or more circuits that enable computation of at least one frequency error value based on one or more previous computed frequency error values, current received symbols, and/or corresponding previously received symbols. A weighted sum may be computed from a plurality of computed frequency error values. A current demodulation frequency may be adjusted based on the computed weighted sum. The adjusted demodulation frequency may be utilized for receiving one or more subsequent symbols.
