Abstract
For boosting decompressionin the presence of reoccurring Huffman trees, a compacted description of a Huffman tree is compared to recently used Huffman tree compactions for identifying matches rather than reconstructing a Huffman tree from a header of a compressed block for each data block to avoid overhead of a Huffman tree reconstruction.
