Abstract :
In this paper, a fine carrier recovery algorithm is proposed to maintain a good performance even with Doppler shifts for OFDM systems. It estimates the frequency offset by utilizing two correlation values for intentionally added positive and negative frequency offsets. Its performance is compared with conventional algorithms such as Beek and Moose algorithms.
