ults in a sinc- shaped frequency localization. As soon as the synchronization in OFDM is lost, the time-domain rectangular pulse shape associated with synthesised subcarriers at the transmitter and analysed subcarriers at the receiver, due to its relatively higher out-of-band (OOB) emission, results in significant leakage of signal power among the band of neighbourhood users [4]. Thus, OFDM-based systems are sensitive to practical impairments such as carrier frequency offset and timing offset, especially in vehicular scenarios where tracking Doppler shifts of different user equipments is challenging. For instance, achieving perfect synchronization in the uplink of orthogonal frequency division multiple access (OFDMA) may not be possible. This happens because each of the users transmits independently from different locations. Attaining synchronization in OFDM-based cognitive radio systems is even more challenging, because primary and secondary users transmit independently and may be operating on distinct standards [5, 6]. In view of the above observations, researchers are motivated to investigate new multicarrier modulation schemes for future wireless communication systems. Such schemes, while outperforming existing solutions in terms of OOB emission, should also ensure similar efficiency and robustness as OFDM. In this context, engineers in Alcatel-Lucent Bell Laboratories have investigated a waveform called universal filtered multicarrier (UFMC) [7], wherein a set of subcarriers assigned to a node are processed through a filter to minimize the multi-node interference. This technique, due to degraded orthogonality among the subcarrier in the existence of multipath fading, results in a performance loss [8]. The second popular waveform is generalized frequency division multiplexing (GFDM), proposed in [9]. In GFDM, each subcarrier is shaped using a well frequency-time (FT) localized filter in circular 3 FBMC: A Waveform Candidate for Beyond 5G fashion such that one CP is attached to a block of Nd information bearin
