  In this paper, we propose a novel waveform design which efficiently combines
two air interface components: Frequency and Quadrature-Amplitude Modulation
(FQAM) and Filter Bank Multicarrier (FBMC). The proposed approach takes the
unique characteristics of FQAM into consideration and exploits the design of
prototype filters for FBMC to effectively avoid self-interference between
adjacent subcarriers in the complex domain, thus providing improved performance
compared with conventional solutions in terms of self-interference, spectrum
confinement and complexity with negligible rate loss.
