Abstract

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.
