Joint Symbol Timing and Channel Estimation for FBMC-OQAM Systems [PDF]
IEEE Access, 2019 Filter bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) can achieve very low out-of-band radiation and is considered to be an important candidate waveform for future communication networks. However, the synchronization sequence design and channel estimation issues are complicated in FBMC-OQAM systems owing to the pulses overlap

Characterization of the effects of multi-tap filtering on FBMC/OQAM systems [PDF]
EURASIP Journal on Advances in Signal Processing, 2014 The filter bank multicarrier modulation based on offset quadrature amplitude modulation (FBMC/OQAM) is being considered as an eligible technology for future wireless communications. However, the orthogonality may be destroyed in the presence of multipath fading, and thus, the demodulated data may be affected by inter-symbol and inter-carrier ...
