摘要

本文提出了一种基于自适应小波包分解的可重构实时音频编码处理器的动态算法变换(DAT)。在给定的嵌入式处理器结构和时间分辨率下，通过最大化每个子带的最小掩蔽阈值(受感知熵的限制)来约束小波变换的最小代价子带分解。

Dynamic algorithm transforms for reconfigurable real-time audio coding processor

In this paper, dynamic algorithm transforms (DAT) for reconfigurable real-time processor for audio coding based on the adaptive wavelet packet decomposition are presented. The DAT technique is used to constrain a minimum cost subband decomposition of wavelet transform by maximizing the minimum masking threshold (which is limited by the perceptual entropy) in every subband for the given embedded processor architecture and temporal resolution.
