摘要：

In this paper, a new single carrier frequency division multiple access (SC-FDMA) system based on the discrete cosine transform (DCT) for uplink wireless transmissions, is introduced. The time domain expressions of the DCT SC-FDMA signals are derived. The peak to average power ratio (PAPR) of the DCT SC-FDMA signals is compared with that of the discrete Fourier transform (DFT) SC-FDMA and orthogonal frequency division multiple access (OFDMA) signals. Simulation results show that the proposed DCT SC-FDMA system provides a better bit error rate (BER) performance than the OFT SC-FDMA and the OFDMA systems. In addition, it is found that the PAPR of the DCT SC-FDMA signals is lower than that of OFDMA signals.
