Abstract

This paper presents a refined coarse frame synchronization algorithm for long repeated-sequence based preamble STF (short training field) in burst mode MR-OFDM system of 802.15.4g which is of low decision delay and resistant to timing uncertainty due to metric plateau. The precision of coarse timing and frequency offset estimation is improved. A fine symbol timing and frequency offset estimation algorithm based on LTF (long training field) is also proposed which provides an overall solution for the synchronization of burst mode MR-OFDM system. Simulation results are given to provide reference for implementation.
