Abstract

Quadrature Amplitude Modulation Filterbank Multicarrier (QAM-FBMC) has been a promising technology for 5G communication systems. However, to achieve the desired performance, it is necessary to deal with the intrinsic interference observed at the receiver. Aiming to overcome the intrinsic interference, in this paper, we evaluate the applicability of a quincunx lattice structure to the QAM-FBMC systems implemented with short filters. We compare and analyze the performance of the QAM-FBMC with rectangular and quincunx lattice structures through the bit error rate (BER) over AWGN and pedestrian fading channels.
