| Abstract | A novel constrained parity-check code with post-processing is presented in this paper for improving the bit error rate performance on perpendicular recording channels. The particular design of the parity-check code results in a post-processor, that is computationally much simpler than conventional post-processors. We also examine the optimality of the post-processors used in current systems. The proposed constrained parity-check code results in about 4.2 dB coding gain, as seen from our analytical and simulation studies |
