Blind Timing Synchronization for Filter-Bank Multicarrier Wireless Communications

We describe the performance of a blind timing recovery algorithm for filter bank multicarrier modulation (FBMCM) modems. Our starting point is a the maximum-likelihood criterion. From that, we present the derivation of a closed-loop tracker and demonstrate how to derive a relatively low-complexity scheme with reasonable performance loss. Unlike previously published works, a remarkable acquisition range equal to plus and minus one half the FBMCM signaling interval is achieved. We also show by simulation a significant robustness with respect to the multipath channel and non ideal carrier frequency estimation.
