Title (EN) SIGNAL CONVERSION METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF DE CONVERSION DE SIGNAL
(KO) 신호 변환 방법 및 디바이스
Abstract:
(EN) A signal conversion method and a signal conversion device are provided. For example, the signal conversion method comprises the steps of: determining a minimum value matrix consisting of minimum values which can be had by the respective elements of a matrix used for frequency conversion, and a maximum value matrix consisting of maximum values which can be had by the respective elements of the matrix; determining an upper threshold for the result value of a function for representing the conversion distortion, normalization, and/or orthogonality of the matrix; determining a conversion matrix consisting of elements which are greater than the elements of the minimum value matrix and smaller than the elements of the maximum value matrix in the respective positions of the matrix, wherein the result value of the function is smaller than the upper threshold; and converting an input signal using the determined conversion matrix.
(FR) L'invention porte sur un procédé de conversion de signal et sur un dispositif de conversion de signal. Par exemple, le procédé de conversion de signal comporte les étapes suivantes : la détermination d'une matrice de valeurs minimales consistant en valeurs minimales qui peuvent être possédées par les éléments respectifs d'une matrice utilisée pour une conversion de fréquence, et une matrice de valeurs maximales consistant en valeurs maximales qui peuvent être possédées par les éléments respectifs de la matrice; la détermination d'un seuil supérieur pour la valeur de résultat d'une fonction pour représenter la distorsion de conversion, la normalisation et/ou l'orthogonalité de la matrice; la détermination d'une matrice de conversion consistant en éléments qui sont supérieurs aux éléments de la matrice de valeurs minimales et inférieurs aux éléments de la matrice de valeurs maximales dans les emplacements respectifs de la matrice, la valeur de résultat de la fonction étant inférieure au seuil supérieur; la conversion d'un signal d'entrée en utilisant la matrice de conversion déterminée.
(KO) 신호 변환 방법 및 신호 변환 디바이스가 제공된다. 예를 들어, 신호를 변환하는 방법은, 주파수 변환에 이용되는 행렬의 각 원소들이 가질 수 있는 최소값으로 구성된 최소값 행렬과 상기 행렬의 각 원소들이 가질 수 있는 최대값으로 구성된 최대값 행렬을 결정하는 단계; 상기 행렬의 변환 왜곡, 정규화 및 직교성 중 적어도 하나를 나타내기 위한 함수의 결과 값의 상한 임계치를 결정하는 단계; 행렬 각 위치에서 상기 최소값 행렬의 원소보다 크고 상기 최대값 행렬의 원소보다 작은 원소로 구성되고, 상기 함수의 결과 값이 상기 상한 임계치보다 작은 변환 행렬을 결정하는 단계; 및 상기 결정된 변환 행렬을 이용하여 입력 신호를 변환하는 단계를 포함한다.
