Abstract
A receiving device includes: a resampler to convert a sampling rate of a reception signal, and output a first signal that is a signal having been subjected to sampling rate conversion; an equalizer to perform an adaptive equalization process using the first signal as an input, and output a second signal that is a signal having been subjected to the adaptive equalization process and having a sampling rate that is an integer fraction of an input signal; a correlation calculator to calculate a correlation function between the first signal and the second signal; and a rate controller to control a rate conversion ratio for sampling rate conversion in the resampler on a basis of the correlation function.

A receiving device comprising:
- a resampler to convert a sampling rate of a reception signal, and output a first signal that is a signal having been subjected to sampling rate conversion;
- an equalizer to perform an adaptive equalization process using the first signal as an input, and output a second signal that is a signal having been subjected to the adaptive equalization process and having a sampling rate that is an integer fraction of an input signal;
- a correlation calculator to calculate a correlation function between the first signal and the second signal;
- a rate controller to control a rate conversion ratio for sampling rate conversion in the resampler on a basis of the correlation function;
- and
- an upsampler to upsample the second signal, wherein
- the correlation calculator calculates a correlation function between the first signal and the second signal having been subjected to upsampling by the upsampler.
