Abstract
In this paper we study the design of expectationmaximization EMbased iterative receivers for lowdensity parity check coded multipleinput multipleoutput orthogonal frequencydivision multiplexing systems with the presence of carrierfrequency offset CFO First starting from the maximumlikelihood principle we devise a novel EMbased pilotaided scheme for joint estimation of CFO and channel coefficients Then this estimator is incorporated into the initialization step of the iterative receiver Simulation results show the effectiveness of our receiver design in combating CFO over unknown frequency selective fading channels
