Abstract :
The turbo code interleaver design problem is considered for relatively large block sizes, where the effect of trellis termination is less marked. An optimised interleaver design technique based on simulated annealing is proposed. The performance is significantly better than the Berrou-Glavieux interleaver without an increase in delay.
