OFDM/FM frame synchronization for mobile radio data communication Warner, William D.

Abstract

A synchronization scheme enabling the use of OFDM/FM in a pure ALOHA environment over a mobile radio channel is proposed, implemented, and tested. The synchronization scheme encodes synchronization information in parallel with data in the same manner in which data is encoded in the OFDM/FM frame. The encoded synchronization information is in the form of tones, centered in reserved frequency sub-channels of the OFDM signal. The receiver uses a correlation detector, implemented in the frequency domain, to accurately acquire synchronization on a packet by packet basis. Experimental results indicate that BER performance with synchronization is achieved to within 1.5 dB of the performance achievable with ideal synchronization.
