On unequal error protection for LZSS compressed data

Abstract

An unequal error protection scheme for Lempel-Ziv-Storer-Szymanski (LZSS) compressed data is proposed. The novel method divides the compressed data into short blocks, which 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 efficient or in terms of decoding delay.
