WebMay 25, 2016 · In contrast, frequency-frequency precoding (FF) results in a DFT-precoded GFDM system, with a spectrum similar to OFDM. In FF mode, data is defined directly in the frequency domain, according to . In this case, one data symbol occupies no more than two frequency bins, assuming a bandlimited transmit filter, such as raised cosine.

WebSingle-carrier FDMA ( SC-FDMA) is a frequency-division multiple access scheme. It is also called linearly precoded OFDMA ( LP-OFDMA ). Like other multiple access schemes (TDMA, FDMA, CDMA, OFDMA), it deals with the assignment of multiple users to a shared communication resource. SC-FDMA can be interpreted as a linearly precoded OFDMA … WebJan 21, 2014 · In this paper a novel adaptive discrete Fourier transform precoded OFDM (POFDM) is proposed and investigated. By means of numerical simulation, the proposed modulation scheme is shown to reduce the peak-to-average power ratio of the transmitted OFDM signal up to 2 dB at 10 -3 clipping rate. As a consequence, a smaller input back …
