摘要

提出了一种LZSS压缩数据的不等错误保护方案。这种新方法将压缩后的数据分成短块，从而实现接近实时的操作。通过应用BCH码和块交织器实现了错误保护。与文献中发现的其他方法相比，所提出的方案在压缩比或解码延迟方面具有更高的效率。

Proteção Desigual de Erros usando Códigos BCH para Dados Compactados com LZSS

—An unequal error protection scheme for LZSS compressed data is proposed. The novel method divides the compressed data into short blocks, what allows for near real time operation. The error protection is obtained through the application of BCH codes and block interleavers. Compared to other methods found in the literature, the proposed scheme is either more efﬁciency in terms of compression ratio or in terms of decoding delay.
