Haotian Zhang is a Principal Engineer of R&D at Broadcom Ltd in Longmont, CO., working on the research and development of advanced read channel and Serdes architectures for data storage systems. He holds PhD (2005) degree in electrical and computer engineering from Carnegie Mellon University, Pittsburgh, PA, and MS (2000) and BS (1997) degrees in electrical engineering from Tsinghua University, Beijing, China. Before his work at Broadcom/Avago/LSI, Dr. Zhang worked at Marvell and Maxtor on signal processing in the area of magnetic recording channels and optical channels..
This paper evaluates the performance of several choices of Reed-Solomon code and shows how a frame-interleaved RS(30,26) code can achieve 1e-15 bit-error rate (BER) in the presence of burst errors. See the authors conclude that, as data rates go higher, current 128b/130b encoding is not a good option as the two-bit 01/10 overhead suffers due to its Nyquist pattern property.
