摘要

本文研究了可逆变长码(RVLCs)的性质，这与构造高效码有关。在基于霍夫曼码的RVLC构造算法中，我们建立了码字段过程与效率限制参数之间的依赖关系。基于这一结果，我们提出了一种具有新的码字选择机制的RVLC构建算法。与其他算法相比，该算法产生了更高效率的RVLCs。

Design considerations for efficient reversible variable length codes

This paper considers the properties reversible variable length codes (RVLCs) that are relevant for construction of highly efficient codes. We establish the dependency between the codeword section process and the efficiency-limiting parameters in the Huffman-code-based RVLC construction algorithm. Using this result, we propose an RVLC construction algorithm with a new codeword selection mechanism. The proposed algorithm yields RVLCs of higher efficiency relative to the other algorithms.
