Abstract :
A postprocessing approach is proposed which uses a single-parity, interleaved block code for correcting the errors made by a Viterbi detector. The code proposed here was simulated for an EPR4 channel with two sets of interleave depth D and code word length N with rates 39/40 and 19/20. Simulation showed a realized coding gain of 1.33 dB at a BER=10-5 and 1.59 dB at a BER=10-6 for the code with 39/40 rate. The corresponding numbers for the code with 19/20 rate are 1.54 dB and 1.76 dB.
