In this thesis we study the feasibility of obtaining acceptable variance values in TDOA UWB based positioning of multiple sources. We define the conditions a time-hopping code must satisfy to mitigate multi-user interference. We design two time-hopping code generators. We propose a TOA estimator. We show simulation results and we conclude that both generated time-hopping code and the proposed estimator reduce the TOA estimation variance and that it is possible to reach the CRB when multiple sources are transmitting. Finally, we prove that TDOA based positioning can achieve a standard deviation of the position error in the order of mm.
