Abstract :
A design rule for mapping optimisation adapted to the turbo-equalisation improved by iterative demapping is presented. It is demonstrated that owing to a carefully designed mapping, different to the classical Gray mapping, bit error rate performance is improved for a frequency-selective channel.
