Abstract
In this contribution, a carrier frequency offset (CFO) estimator for OQAM-OFDM systems based on the conjugate symmetry property of a properly designed synchronization sequence is proposed. It extends the concept of a previously described symbol-timing and phase offset recovery scheme to build a complete time-domain synchronization method. The outcome of numerical evaluations shows that the proposed CFO estimation algorithm is suitable as a coarse CFO correction for continuous stream transmission systems. It delivers satisfying results in case of AWGN channels as well as for channels with moderate delay spreads while exhibiting the drawback of a high sensitivity to symbol timing errors. Furthermore, the possibility to reduce the overhead of the synchronization sequence by allowing a certain amount of self-interference is investigated.
