Abstract
In orthogonal frequency division multiplexing systems, the carrier-frequency offset can be divided into two parts: (1) an integer one-multiple of the subcarrier spacing 1/T and (2) a fractional one-less than 1/2T in amplitude. Some schemes proposed in the literature can only recover the fractional part. We derive two algorithms for estimating the integer part. They are based on the observation of two consecutive OFDM symbols. The first algorithm exploits pilot symbols multiplexed with the data, the other is blind.
