DFT Spread C-DSLM for Low PAPR FBMC with OQAM Systems

Filter bank multicarrier system (FBMC) is a part of multicarrier scheme which segmented large frequency spectrum into several narrow subchannels. During the coherent addition at the transmitter end, the peak powers increased N times the average value of powers of all N subcarriers which cause the linearity of high power amplifier. To avoid this, the peak power is reduced so that the ratio of peak power to the average power (PAPR) is evaluated using selective mapping (SLM) scheme. While analyzing computational complexity, it found practically high. So that a discrete Fourier transform (DFT) spread, converse vectors with less complex, dispersion-based SLM, named as DFT spread C-DSLM, is anticipated for less PAPR and computational complexity of FBMC with offset QAM scheme. Simulation results expose that the parameters like PAPR, BER, and computational complexity are proved as better. So the proposed DFT spread C-DSLM scheme offers better performance than existing one.
