Abstract
Official abstract text for this publication.
A receiver includes: a frequency-characteristic-changing-circuit to change a frequency characteristic of an input signal in which N-level data value is pulse-amplitude-modulated, to generate a frequency-characteristic-changed-signal; a controller to control the frequency-characteristic-changing-circuit to obtain a desired ratio between a amplitude component of a target data value corresponding to the frequency-characteristic-changed-signal at a first timing and a second amplitude component thereof at a second timing which is later than the first timing; and a decision-feedback-equalization-circuit to which the frequency-characteristic-changed-signal is input, wherein the decision-feedback-equalization-circuit includes: a comparison-circuit to include comparators each to output a comparison result obtained from comparing the target data value and a threshold value, and N−1 selection circuits each to select one of comparison results output from the comparators at the second timing, based on the comparison results, and wherein at least one of the comparators outputs the comparison results to two of the N−1 selection circuits.
First claim
Opening claim text (preview).
What is claimed is: 1. A receiver comprising: a frequency characteristic changing circuit configured to change a frequency characteristic of an input signal in which N-level data value is pulse-amplitude-modulated, to generate a frequency characteristic changed signal, wherein the N is an integer of 4 or more; a controller configured to include at least a processor configured to control the frequency characteristic changing circuit to obtain a desired ratio between a first ampli…
