METHOD AND DEVICE FOR UPDATING REFLECTION COEFFICIENT OF LATTICE TYPE FILTER

摘要

PROBLEM TO BE SOLVED: To provide a method and device for updating the reflection coefficient which can be used for reducing the number of division calculations required for updating the reflection coefficient of a lattice type filter and for allowing the lattice type filter to be used to identify the characteristics of an unknown system.;SOLUTION: The method for updating the reflection coefficient of the lattice type filter updates the reflection coefficient so as to minimize a forward prediction error.;COPYRIGHT: (C)2001,JPO
