Patent attributes
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.
