摘要

本文以音频信号编码为例，介绍了Golomb码族的优点。如计算复杂度低、效率高、灵活适应编码数据的局部概率分布变化等特点。比较了前向自适应的Golomb编码器和三种版本的反向自适应编码器的有效性。此外，本文还尝试解决编码音频数据分布不完全适应于单侧几何分布的问题，其中Golomb码是最优编码。

Application of adaptive Golomb codes for lossless audio compression

In this paper the advantages of the Golomb codes family on example of audio signals coding are presented. Such as low computational complexity, high efficiency and flexibility to adapt to local changes in the probability distribution characteristics of coded data. The effectiveness of the Golomb coder with forward adaptation with three versions of the reverse adaptation coder has been compared. Also, attempts have been made to solve the problem of incomplete adaptation to the distribution encoded audio data to a one-sided geometric distribution, for which the Golomb code is the optimal code.
