FREQUENCY DOMAIN AUTOMATIC EQUALIZER UTILIZING THE DISCRETE FOURIER TRANSFORM

摘要

FREQUENCY DOMAIN AUTOMATIC EQUALIZER UTILIZING THE DISCRETE FOURIER TRANSFORM An automatic equalizer for calculating the equalization transfer function and applying same to equalize received signals. The initial calculation as well as the equalization proper are conducted entirely within the frequency domain. Overlapping moving window samplings are employed together with the discrete Fourier transformation and a sparse inverse discrete Fourier transformation to provide the equalized time domain output signals.
