Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A receiver device comprising:
a first equalizer circuit configured to receive a first signal from outside, the first equalizer circuit boosting the first signal to output a resultant as a second signal;
a first sampler circuit configured to sample the second signal, the first sampler circuit outputting a sampling result of the second signal as a first digital signal; and
a control circuit configured to execute adaptive processing for adapting an amount of boost for the first signal by the first equalizer circuit to a loss of the first signal, wherein
in the adaptive processing, the control circuit is configured to:
adjust the amount of boost for the first signal based on inter-symbol interference of a part in the first digital signal, the part matching a data pattern of a set pattern filter; and
dynamically change a pattern filter to be set according to the amount of boost for the first signal.
