Abstract: This paper designs a new class of codes:parallel concatenated extended Hammin codes using a combination of multi-dimensional parallel concatenation and extension techniques. The encoder is built using a parallel concatenation of multiple extended Hamming codes. The decoder uses the iterative decoding of the maximum a posterior algorithm based on the trellis technique, discussed in the paper.

Key words: coding, parallel concatenated extended Hammin codes, decoding
