Demodulation method e.g. for multi-carrier transmission system, involves recording information whether impulse noise is present and demodulating signal transmitted over multi-carrier transmission system

摘要

The method involves recording information (35) whether an impulse noise is present and demodulating a signal transmitted over a multi-carrier transmission system. The information is evaluated for the presence of impulse noise. The information (35) recorded being present in impulse noise is information (11, 12) from different frequency ranges and correlated with one another and a decision made whether impulse noise is present and the result (y 2()) over a pre-determined threshold value (r) is appropriate for the correlation. The information (11, 12) from the different frequency ranges is correlated with one another, as initial values (11, 12) for a Fourier transformation (2) procedure. The procedure for the Fourier transformation (2) is a component of the demodulation (1) of the multi-frequency modulation system. An independent claim is included for a device.
