Erasure Detection Algorithms for Magnetic Recording Channels
Weijun Tan, Haitao Xia, J.R. Cruz · IEEE Transactions on Magnetics · 2004
The effects of precoding on the detection of erasures based on violations of run-length-limited (RLL) constraints for low-density parity-check (LDPC) coded magnetic recording channels are investigated and an improved erasure detection algorithm is proposed. Its performance on an ME/sup 2/PR4 channel is evaluated using computer simulations.
