Abstract

A new technique to recover the carrier frequency offset of OFDM systems is proposed. The proposed technique does not require cyclic prefix, pilot signals, training symbols, or any other supplementary data, this will significantly improve the system power and bandwidth efficiency. The proposed algorithm exploits the interference that results due the loss of orthogonality between subcarriers where the variance of the resulted interference is proportional to the carrier frequency offset. The proposed technique does not require prior fine symbol synchronization and it is capable of estimating the carrier offset at Eb/N0 as low as -3 dB with symbol timing offset that is less than or equal to 10% of the symbol duration.
