Abstract

A new technique, called generalised array coding (GAC), is proposed. The proposed technique allows the design of array codes with higher information rate, while the size of array and the minimum code distance remain the same. An example is given for (16, 11, 4) array code, however the proposed technique is applicable to all existing codes. It is shown that the trellis structure of such codes provides lower decoding complexity compared with conventional techniques.
