Abstract:	This paper deals with the problem of multipath mitigation using a Particle Filtering (PF) approach. We describe two PF algorithms already proposed by the authors in [1] and [2]. The aim of the present paper is to compare both alternatives in terms of particle efficiency, that is, to study the required number of particles to achieve a certain tracking precision. The efficiency issue is of high importance when a PF implementation is envisaged since reducing the number of samples has a direct impact in the required computational resources.
