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 … WebDec 10, 2015 · Delay spread can be detrimental to communication systems. Orthogonal Frequency Division Multiplexing (OFDM)/Discrete Fourier Transform-spread-OFDM (DFT-s- OFDM) based systems (for e.g., Long Term Evolution (LTE), WiFi, etc.) tackle delay spread by adding a cyclic prefix (CP) before the start of the OFDM symbol. The duration of the …

WebThe PAPR of 16QAM is also higher than that of QPSK. However, even when these symbol types are the same, the PAPR of DFT-SPREAD OFDM is still lower than that of regular OFDM. The reason is the (N point) IDFT effect is mostly cancelled out by the (M point) DFT. If the M=N (no zero), they are completely canceled out and the symbols would be just a ...
