Improved Preamble-Aided Timing Estimation for OFDM Systems
Awoseyila, AB, Kasparis, C and Evans, BG (2008) Improved Preamble-Aided Timing Estimation for OFDM Systems IEEE Communications Letters, 12 (11). 825 - 827.
An improved method for estimating the frame/symbol timing offset in preamble-aided OFDM systems is presented. It uses a conventional preamble structure and combines autocorrelation techniques with restricted cross-correlation to achieve a near-ideal timing performance without significant increase in complexity. Computer simulations show that the method is robust in both AWGN and fading multipath channels, achieving better performance than the existing methods.
