Title:
トランバーサルフィルタのタップ係数制御装置及びタップ係数の制御方法、光受信装置並びに光通信システム
Document Type and Number:
Japanese Patent JP5157536
Kind Code:
B2
Abstract:
An apparatus includes an oscillator circuit configured to generate a certain oscillation signal, an adder configured to add the oscillation signal to the tap coefficient of any of one or more taps of the transversal filter, a signal-quality measurer configured to measure a signal quality of a signal output from the transversal filter, and a tap-coefficient adjuster configured to control the value of the tap coefficient so that an optimal amount of shift in the signal quality of the output signal is achieved when the oscillation signal is added to the tap coefficient.
