Abstract

In this paper we address the problem of joint tracking the channel state and the multiple frequency offsets in MIMO-OFDM systems based on a Sequential Monte Carlo filtering approach. In contrast to most of the existing approaches, a separate frequency offset for each MIMO branch is considered and furthermore the proposed tracking procedure is blind.
