Abstract

An automatic frequency control (AFC) method intended for compensation of a measurement error of an FSK signal central frequency is proposed. The method is based on a frequency error tolerant symbol and frame timing recovery method [1]. The AFC method provides computational efficiency improvement compared to conventional DC offset estimation method.
