Abstract

See full text

A receiver receives frequency division multiplexing transmission signals of multiple carriers, and includes a difference detection unit, an integration unit, a noise detection unit, a selection unit, and a correction unit. The difference detection unit calculates a difference that is representative of the amount of noise in the frequency division multiplexing transmission signals. The integration unit integrates for each frequency of the multiple carriers the difference output of the difference detection unit. The noise detection unit determines whether or not impulse noise is present in the input signal. When impulse noise is present, the selection unit supplies the integrator output to the correction unit. When impulse noise is not present, the selection unit supplies the calculated difference output to the correction unit.
