Abstract

This paper proposes a novel precoding method using the pruned DFT (pDFT) spread FBMC along with the Poly-phase network (PPN). This method outperforms the pruned DFT spread FBMC in many aspects and also avoids Inter symbol Interference. This technique has advantages of both FBMC-Offset Quadrature amplitude modulation (OQAM) and Single carrier Frequency division multiple access (SC-FDMA).Proposed technique has same PAPR as SC-FDMA and has very low out-of-band emissions and does not need cyclic-prefix. This method reduces latency, computational complexity and complex orthogonality is restored. A comparative performance is also evaluated between pDFT-FBMC PPN and other multicarrier schemes and we observe that pDFT-FBMC PPN is better than other schemes. Simulation is performed by using Matlab.
