Synchronization of FBMC based on CAZAC sequence

A synchronization algorithm for FBMC is proposed by combination of CAZAC sequence. Using the CAZAC sequence as the pilot symbols, timing synchronization and frequency synchronization of the FBMC system are realized. Considering the effect of fading on the synchronization, the algorithm combining the CAZAC sequence is rational. Computer simulations verify that the estimation error is about 1e-4 under ordinary signal to noise ratio conditions.
