Abstract

This paper proposes a burst synchronization scheme with a short preamble signal for high data rate wireless LAN systems that use orthogonal frequency division multiplexing (OFDM). The proposed scheme, which consists of automatic frequency control (AFC) and symbol timing detection, enables us to shorten the preamble length to 1/4 that of a conventional one. Computer simulation results show that the degradation in required E_b/N₀ due to the synchronization scheme is less than 1 dB in a selective Rayleigh fading channel
