Maximum likelihood based estimation of frequency and phase offset in DCT OFDM systems under non-circular transmissions: algorith
Recently, the advantages of the discrete cosine transform (DCT) based orthogonal frequency-division multiplexing (OFDM) have come to the light. We thus consider DCTOFDM with non-ci...

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...
