Method for estimating frequency and/or phase of digital signal sequence e.g. for mobile RF technology, involves estimating frequency using discrete Fourier transform

摘要

A method for estimating the frequency (delta F) and/or the phase (phi) of a digital input signal sequence (XV) involves carrying out a frequency rough estimation (22) using discrete Fourier transform and subsequently carrying out a frequency fine estimation by interpolation. Independent claims are also included for the following: (1) A device for estimating the frequency and/or phase of a digital input signal sequence. (2) A digital storage medium with electronically readable control signal; (3) A computer program product; and (4) A computer program with program code devices.
