Abstract
An adaptive receiver comprises a receiver module that receives an orthogonal frequency division multiplexing (OFDM) signal. An operating parameters module monitors at least one operating parameter of the receiver module and generates a select signal based the at least one operating parameter. An estimator module selects between first and second algorithms based on the select signal and selectively estimates a carrier frequency offset (CFO) of the OFDM signal using the one of the first and second algorithms. Alternately, an estimator module adjusts algorithm operating parameters of a first algorithm based on the select signal and selectively estimates a carrier frequency offset (CFO) of the OFDM signal using the selected algorithm operating parameters of the first algorithm.
