This paper presents a reduced complexity frequency offset estimation method as a modification to the nonlinear least square (NLS) method. The complexity reduction is achieved by utilizing the Chirp-Z transform. At similar complexity, the estimation performance gain, de-fined as the mean square error ratio between the NLS method and the proposed method, can be approximately from 1.5 dB to 8.5 dB depending on the operating SNR value. The paper also presents a modified training structure that can give approximately from 2.5 dB to 10.5 dB estimation performance gain over the training structures of and IEEE 802.11a.
