Abstract
A receiver device according to an embodiment includes a equalizer, a sampler, and a controller. The equalizer receive a first signal. The equalizer boosts the first signal to output a resultant as a second signal. The sampler samples the second signal. The sampler outputs a sampling result of the second signal as a first digital signal. The controller executes adaptive processing for adapting an amount of boost of the first signal. In the adaptive processing, the controller is configured to: adjust an amount of boost for the equalizer 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 equalizer.

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.
A reception method of a receiver device comprising:
- boosting a first signal received from outside;
- sampling a second signal to generate a first digital signal, the second signal being the boosted first signal;
- and
- executing adaptive processing for adapting an amount of boost for the first signal to a loss of the first signal;
- the adaptive processing comprising:
- adjusting 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
- changing dynamically a pattern filter to be set according to the amount of boost for the first signal.
