Synchronization is one of the key techniques for OFDM systems and it is of importance to implement synchronization quickly and reliably in practical OFDM systems. In this paper, we implement the synchronization method on TI C55X DSP platform for OFDM-based trunking communication system with FDD scheme, and mainly focus on the tradeoff between accuracy and complexity by combining linear interpolation and look-up table method in order to satisfy the requirement of practical application. Numerical results are presented to show the effectiveness of the proposed scheme.
