Abstract

In this paper, we consider the problem of joint channel and frequency offset estimation, data detection in a flat-fading multi-input multi-output (MIMO) system. We assume that each pair of transmit and receive antennas has a different frequency offset value. We present a computationally efficient iterative algorithm based on the space-alternating generalized expectation-maximization (SAGE) and the expectation conditional maximization (ECM) algorithms.
