Abstract— Since carrier frequency offset destroys user’s signal orthogonality in Orthogonal Frequency-Division Multiplexing Access (OFDMA) uplink transmission, resulting in an ...
In this paper, we present a comparison between the sensitivity of SC-FDMA and OFDMA schemes to large carrier frequency offsets (CFO) and timing offsets (TO) of different users on t...
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 ...
