In this paper, a novel OFDM synchronization scheme with adaptive blind parameters detection is proposed, which utilizes a fast estimation method to obtain the key OFDM system parameters, including the FFT points number (2K/4K/8K mode) and the length of guard interval. These parameters guarantee the accuracy of the further system synchronization. Besides, the proposed scheme is also a joint solution, which realizes the blind parameter detection, symbol recovery and frequency synchronization in the same process. Due to such novel scheme and its further sign-bit implement optimization, circuit implementation complexity of the synchronization block is reduced greatly to a quite impressive 8.3% of that while using the traditional scheme.
