摘要：The method involves conducting a frequency pre-estimation (49) to determine apre-estimate value (delta f hat pre) with a first maximum likelihood estimate using part ofthe sequence length, conducting a frequency compensation of the digital input sequenceusing the pre-estimate to produce a frequency compensated sequence, conducting amain estimation (58) to determine a main estimate value (delta f hat main) with a secondmaximum likelihood estimate using the frequency-compensated sequence and addingthe pre-estimate and main estimate to a total estimate (delta f hat) of the frequency.Independent claims are also included for the following: (a) a device for estimating thefrequency and/or phase of a digital signal sequence (b) a digital memory medium forinteracting with a computer or digital signal processor for implementing the inventivemethod (c) a computer program product for implementing the inventive method (d) anda computer program for implementing the inventive method.
