ScholarBank@NUS Repository. https://doi.org/10.1109/TWC.2008.060605 | Abstract: | In this paper, we consider the problem of joint channel and frequency offset estimation in a flat-fading multiinput multi-output (MIMO) system. We assume that each pair of transmit and receive antennas has a different frequency offset. We present two computationally efficient iterative algorithms based on expectation conditional maximization (ECM) and space-alternating generalized expectation-maximization (SAGE) algorithms. The mean-square-error (MSE) performance of the interested parameters for the proposed algorithms is compared with the Cramér-Rao Bound (CRB). Simulation results show that the proposed iterative algorithms achieve the CEB and overcome the drawbacks of existing algorithms. © 2008 IEEE. | Source Title: | IEEE Transactions on Wireless Communications | URI: | http://scholarbank.nus.edu.sg/handle/10635/56435 | ISSN: | 15361276 | DOI: | 10.1109/TWC.2008.060605 |
