Patent ID: 8750366

Claim:
An equalization device comprising: a first sample hold unit that samples and holds an input signal modulated at a period of a predetermined symbol length; a first multiplication unit that multiplies an output signal of said first sample hold unit by a first coefficient; a second sample hold unit that samples and holds the input signal at a timing delayed from a sample hold timing of said first sample hold unit by one symbol length of the input signal; a second multiplication unit that multiples an output signal of said second sample hold unit by a second coefficient; and an addition unit that adds an output signal of said first multiplication unit and an output signal of said second multiplication unit to output a sum signal, wherein the first coefficient and the second coefficient are determined such that a first post-cursor is removed from the output signal of said first multiplication unit when the output signal of said multiplication unit and the output signal from said second multiplication unit are added by said addition unit.
