Résumé

We consider an ultra wide band impulse radio multiple access scheme based on time-hopping code under a realistic multipath channel model. As a novelty, we provide a closed-form expression for the variance of the multi-user interference at the output of the rake receiver of the user of interest. That enables us to characterize the optimal time-hopping codes minimizing the multi-user interference variance. Finally we observe through simulations that minimizing the multi-user interference variance translates into better performance by significantly decreasing the error probability.
