Error Correction Code Failure Rate Analysis for Parity-Check-Coded Optical Recording Systems

We propose semi-analytical approaches for estimating the failure rate of interleaved error correction code (ECC) for parity-check (PC)-coded optical recording systems. We demonstrate the accuracy of the proposed approaches using simulation results. We further evaluate the ECC failure rate (EFR) of a PC-coded optical recording system. The analysis shows that with optimum interleaving degrees, the 4-bit constrained PC code achieves a gain of 0.6 dB over the rate 9/13 code without parity at EFR = 10(-16).
