Application of a genetic algorithm to Hopfield network multi-user detection

In this study, a hybrid approach that employs Hopfield network and a genetic algorithm for multi-user detection problem in Code Division Multiple Access system is proposed. The hybrid detection makes use of the global convergence advantage of the genetic algorithm to deal with the output of the Hopfield network detection. So the novel detection will not converge on the minimum of local energy function as the Hopfield network detection. And the computer simulation results show that this detection has good performance both in multiple-access interference resistance and near-far effect resistance.
