Title:
PARAMETER INTERPOLATION DEVICE AND METHOD THEREFOR
Document Type and Number:
Japanese Patent JP3555925
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To estimate a lost parameter corresponding to the state of signals and to perform highly accurate parameter estimation.
SOLUTION: When a code error is detected in a communication path and the parameter mapped by a mapping device 101 is lost, the lost parameter is estimated by a parameter estimation device 103. A model state updating device 102 updates the state of a parameter generation model by using a decoded parameter and the parameter estimation device 103 estimates the parameter by using the model state.
