Abstract :
A parallel genetic algorithm is applied to assign the codevector indices for noisy channels so as to minimise the distortion caused by bit errors. The property of multiple global optima and the average distortion of the memoryless binary symmetric channel for any bit error are also introduced. Experimental results confirm this approach
