Title:
ADAPTIVE EQUALIZER AND ADAPTIVE EQUALIZING METHOD
Document Type and Number:
WIPO Patent Application WO/2001/065723
Kind Code:
A1
Abstract:
A training section (102) calculates a tap coefficient. An impulse response calculating section (103) calculates the impulse response of the tap coefficient. A tap selecting section (104) selects a tap on the basis of the magnitude of the impulse response. A replica generating section (105) multiplies a symbol for generating a replica by the tap coefficient for only the selected tap, and thereby generates a replica under the control of a control section (106) so that the same replica may be not generated duplicately.
