Application of erasure error correction to concatenated partial-response channel code

Abstract

Erasure error correction based on List-SOVA has been applied to partial-response channel code for high-density magnetic recording. Soft-output information extracted from modified EEPR4ML is used. To achieve as high a total coding rate as possible, a 16/17MTR(3;11) code and a rate 544/561 cyclic redundancy check code (CRCC) are combined. CRCC-false-correction deteriorates erasure error correction performance. To solve this problem, a method for detecting CRCC-false-correction has been proposed. Simulation results show that our method can reduce block error rates to 1/10 the case without erasure error correction at the user density of 2.8.
