TLDR
In this paper, the decoding of BCH multiple error correction code codewords with α as a primitive element of the finite field GF (2m) is accomplished by generating syndrome subvectors S1 from all column m-tuple αk positions and syndrome subvector S2 from all table m-touple α3K positions, and then selecting those bit positions K where S1 3 +S2 +QK=0 as the bit or bits in error.
Abstract
Decoding of BCH multiple error correction code codewords with α as a primitive element of the finite field GF (2m) is accomplished by generating syndrome subvectors S1 from all column m-tuple αk positions and syndrome subvectors S2 from all column m-tuple α3K positions, generating a permutation of syndrome subvector S1 for each bit position on the codeword and then selecting those bit positions K where S1 3 +S2 +QK=0 as the bit or bits in error.
