Abstract :
We propose a filter-bank multicarrier (FBMC) system to transmit quadrature amplitude modulation (QAM), which can suppress sidelobe level of the odd prototype filter. We present low-pass filtering method obtaining frequency confinement property for the odd filter. Bit error rate (BER) performance shows that the proposed odd filter can enhance the FBMC system in multipath fading channels compared to the conventional QAM-FBMC system.
