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...
