Filter bank (FB) multicarrier modulation exhibits several properties which make it an attractive approach not only for high speed copper wire communications networks but also for broadband wireless applications. In this paper, we derive a nondata aided carrier frequency offset recovery algorithm for wireless FB-based systems. The estimator is based on a maximum likelihood approach and has a feedback loop structure. A number of proper simplifications make the problem tractable and allow to reduce the computational complexity. The algorithm accuracy is examined by computer simulation for AWGN and frequency selective multipath channel showing an considerable robustness against timing errors.
