摘要：
The performance of nested error-correction codes for perpendicular magnetic recording channels is evaluated in the presence of burst noise using Reed-Solomon codes as well as low-density parity-check codes as component codes. Erasure detection and iterative decoding algorithms for nested codes are considered, and their performance is evaluated using computer simulations. The results illustrate the advantages of the nested schemes over noninterleaved architectures in terms of sector error rate and complexity for both current and future native block sizes.
