Burst Error Performance of LDPC codes on Perpendicular Magnetic Recording Channel
Sangin Kim, Jaejin Lee · 2008
In this paper, we analyze the burst error performance of LDPC codes on perpendicular magnetic recording(PMR) channel. When burst error is generated on PMR channel, we use channel state information(CSI) to set the LLR information of channel detector zero. We consider the rate 0.94 LDPC codes and use SOVA as channel detector with low complexity.
