dc.description.abstract | 본 논문은 AMR-WB+ 코덱의 오디오 품질을 개선하기 위하여 TCX모듈 변환계수 양자화기에 8차 및 16차Pyramid VQ 방식을 응용하였다. 제안된 Pyramid VQ 방식은 AMR-WB+ 코덱에 적용된 RE8 Lattice VQ 방식과 비교 평가 되었으며, 8차 및 16차 Pyramid VQ 방식의 사용시 Mean Squared Error(MSE)는 각각 4% 및 5.7% 개선되었고, Perceptual Evaluation of Audio Quality(PEAQ) 값은 각각 3.3% 및 4.7% 개선되었다. In this paper, we Propose a pyramid VQ to quantize the transform coefficients of TCX module for the audio improvement of AMR-WB+ codec. The Proposed pyramid VQ is compared to the RE 8 RE8 Lattice VQ used in the AMR-WB+ standard codec. demonstrating improvement 4% and 5.7%. respectively, in Mean Squared Error (MSE) and 3.3% and 4.7%. respectively, in Perceptual Evaluation of Audio Quality (PEAQ) by 8-dimensional and 16-dimensional Pyramid VQ. | en_US |
