FPGA implementation of Generalized Frequency Division Multiplexing transmitter using NI LabVIEW and NI PXI-platform

摘要

GFDM is a filtered multicarrier modulation scheme that can transmit sequences of circularly pulse shaped symbols per subcarrier with or without cyclic prefix extension. GFDM can perform OFDM (Orthogonal Frequency Division Multiplexing) as a special case when configured to transmit one square pulse shaped symbol per subcarrier. Its flexibility to provide localized spectrum properties has the potential to alleviate issues of synchronization and carrier aggregation in future wireless communication systems. This article presents preliminary results of a proof of concept implementation of the transmitter using a NI PXI-software defined radio platform and the NI LabVIEW FPGA module.
