✦ Synopsis

The authors present a new approach to search for the best code and best depth value of the interleaver process for fading channels using genetic algorithms. Traditionally, the optimization of communication systems is performed using an a priori evaluation function and Monte Carlo simulations. However, by the use of a posteriori evaluation functions and genetic algorithms, direct performance of the best codes and best interleaver for fading channels is achieved. The double checking performance associated with the a priori procedure is eliminated by a remarkable simplification of the design of mobile ratio and satellite communication systems. Performance and complexity are also evaluated.
