“A Spectrum Coding And Decoding Apparatus And Methods Thereof”
Abstract: The present invention relates to a spectrum coding apparatus comprising an acquisition section that acquires a first spectrum which frequency k is in a band of 0 ≤ k < FL; an acquisition section that acquires a second spectrum which frequency k is in a band of 0 ≤ k < FH; an estimation section that estimates the shape of said second spectrum in a band of FL ≤ k < FH by the following expression ) ( ) ( T k S k S − = where S(k) in 0 ≤ k < FL is the first spectrum, S(k) in FL ≤ k < FH is the estimated second spectrum, and T is a pitch coefficient; and a coding section that codes a pitch coefficient minimizing a distortion between the shape of the estimated second spectrum and the shape of said second spectrum in the band of FL ≤ k < FH.
