Abstract:
In this paper, we analyze different designed pilot patterns adapted to the DL-PUSC pilot grid for filter banks multi-carrier (FBMC) system. Different scheme have been proposed (pair of pilots, auxiliary pilot scheme, interference approximation method, and Scattered pilot method) and their performance evaluated and compared when using conventional cyclic prefix orthognal frequency division multiplaxing (CPOFDM)system. We shown that by applying certain designed patterns especially for filter banks multi-carrier, the bite error rate can outperforms in certain cases that achieved by the CP-OFDM system. The performance evaluations are done in hypothetical WiMAX scenario on which the FBMC system will substitute the CP-OFDM by maintaining as much as possible the physical layer (PHY) compatibilities.
