  Abstract

This paper proposes a symbol synchronization method in the IEEE 802.11a wireless LAN system, which uses only signs of the in-phase and the quadrature signals in the short preamble. The short preamble is sampled with 2 times of Nyquist sampling rate and both of the autocorrelation and the cross-relation are used in the proposed method. This method has some advantages that the AGC (Automatic Gain Control) can be processed concurrently during the short preamble and its implementation is not much complicated. The proposed symbol synchronization method is verified through simulations on frequency offset, multi-path, and white Gaussian noise.
