Carrier frequency offset (CFO) in MIMO-OFDM systems can be decoupled into two parts:fraction frequency offset (FFO) and integer frequency offset (IFO).The problem of IFO estimation is addressed and a new IFO estimator based on the Bayesian philosophy is proposed.Also,it is shown that the Bayesian IFO estimator is optimal among all the IFO estimators.Furthermore,the Bayesian estimator can take advantage of oversampling so that better performance can be obtained.Finally,numerical results show the optimality of the Bayesian estimator and validate the theoretical analysis.
Carrier frequency offset (CFO) in MIMO-OFDM systems can be decoupled into two parts: fraction frequency offset (FFO) and integer frequency offset (IFO). The problem of IFO estimation is addressed and a new IFO estimator based on the Bayesian philosophy is proposed.Also, it is shown that the Bayesian IFO estimator is optimal among all the IFO estimators. Still more, the Bayesian estimator can take advantage of oversampling so that the better performance can be obtained. Finally, numerical results show the optimality of the Bayesian estimator and validate the theoretical analysis.
