Abstract

Abstract:

A new OFDM frame synchronization algorithm is proposed, two identical sequences are included in the synchronized symbol. The diversity of multipath channel is considered in the new object function so that performance of the proposed algorithm will be not influenced by frequency selectivity of channel. Analytical form of missing detection and false detection probability of the proposed algorithm are given. Numerical simulations validate the analytical results: when the receiver’s SNR is 20dB and missing detection probability is 10-10, the false detection probability tends to zero in our algorithm.

Key words: orthogonal frequency division multiplex, synchronization, multipath fading channel, carrier frequency offset
