Abstract
In this paper we proposed a complete orthogonal frequency division multiplexing (OFDM) synchronization chain by using PN sequence. In multi-path channel, the frequency estimation precision of this method is better than conventional method for it using multi-path signals. The result of compute simulation indicates that the proposed synchronization chain based on PN sequences can make precise synchronization in low SNR and also can satisfy the demand of OFDM system at moderate moving rate in Rayleigh channel or AWGN channel.
