Title:
特徴パラメータ生成装置、特徴パラメータ生成方法および特徴パラメータ生成プログラム
Document Type and Number:
Japanese Patent JP5763414
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To generate a feature parameter while suppressing increase in a circuit/software scale and also considering dispersion of feature-parameter time series.SOLUTION: A feature parameter generation device 100, for reproducing distribution of feature-parameter time series corresponding to serial information of a symbol, is configured to generate time series data of a feature parameter by modifying the time series data of an initial value so that the distribution of the feature parameter becomes a maximum likelihood, and perform modification of the initial value and repetition of modification using, of configurations for repetitively modifying the time series data of the generated feature parameter, the same configuration (modification data generation part 120) so as to increase the likelihood of the distribution of the feature parameter and the dispersion of the time series data of the feature parameter. As such, the modification of the initial value and the repetitive modification with the same configuration eliminate a need to dispose a circuit and software in duplication, enabling reduction in circuit and software scales.
