The matched filter bank comprises an input for receiving data representative of a frequency- or phase-modulated signal. The decision logic generates a sequence of demodulated symbol values from outputs of the matched filter bank. The frequency offset estimator determines a first phase value from a first output and a second phase value from a second output of the matched filter bank, the second output being offset from the first by L symbol periods. It also determines a phase adjustment value from an L-symbol subsequence within the sequence of demodulated symbol values, each subsequence value being determined from values output by the matched filter bank between the first and second outputs. It estimates a frequency offset based on the difference between the first phase value plus the phase adjustment value, and the second phase value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frequency offset estimation","description":"A receiver comprises a matched filter bank, decision logic and a frequency offset estimator.
