The Effect of Imperfect Carrier Frequency Offset Estimation on OFDMA Uplink Transmission
Abstract— Since carrier frequency offset destroys user’s signal orthogonality in Orthogonal Frequency-Division Multiplexing Access (OFDMA) uplink transmission, resulting in an ...

Robust frequency synchronization for an OFDMA uplink system disturbed by a Cognitive Radio system interference
In Cognitive Radio (CR) systems, spectrum sensing plays a key role to determine the free frequency bands. However, when the primaryuser (PU) signal spectrum exhibits localized fad...
