Abstract—A frequency offset compensation method for OFDMFDMA, that can correct offsets after the DFT via circular convolution, is proposed as an alternative to the direct method ...

Abstract— Since carrier frequency offset destroys user’s signal orthogonality in Orthogonal Frequency-Division Multiplexing Access (OFDMA) uplink transmission, resulting in an ...
— In orthogonal frequency-division multiplex access (OFDMA) systems, including uplink and downlink, the carrierfrequency offset (CFO) between the multiple transceivers introduces...

In this paper, we propose a joint estimation method of carrier frequency offsets (CFO) and channel impulse responses (CIR) for an uplink OFDMA system. We consider the CFOs come in...
