Abstract

Abstract

A new OFDM decision-directed carrier frequency offset tracking algorithm is presented. High precision, low computational efforts and simple implement are obtained with the new algorithm. And an improvement method is also described which enhances the capacity of resist frequency selected fading channel, based on channel information. With this method, the tracking performance at low SNR is improved.
