This paper discusses bit-level soft decoding of triple-parity Reed-Solomon\n(RS) codes through automorphism permutation. A new method for identifying the\nautomorphism groups of RS binary images is first developed. The new algorithm\nruns effectively, and can handle more RS codes and capture more automorphism\ngroups than the existing ones. Utilizing the automorphism results, a new\nbit-level soft-decision decoding algorithm is subsequently developed for\ngeneral (n,n-3,4) RS codes. Simulation on (31,28,4) RS codes demonstrates\nan impressive gain of more than 1 dB at the bit error rate of 10-5 over\nthe existing algorithms.\n
