Abstract

This paper proposes of implementing a diminished DFT (d-DFT) precoded Filter bank multicarrier (FBMC). We develop an efficient precoding method using d-DFT by combining with one-tap scaling. This technique has advantages of both FBMC-Offset Quadrature amplitude modulation (OQAM) and Single carrier Frequency division multiple accesses (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 and complex orthogonality is restored at a considerable computational complexity. A comparative performance is also evaluated between d-DFT-FBMC and other multicarrier schemes and we observe that d-DFT is better than other schemes. Simulation is performed by using Matlab.
