port of diverse service requirements [1, 2]. To address the mentioned limitations of OFDM, several candidate waveforms and their variants, such as filter bank multicarrier (FBMC) [3, 4], generalized frequency division multiplexing (GFDM) [5, 6], and universal filtered multicarrier (UFMC) [7] are being stud- ied and promoted. The comparisons among these schemes with respects to different cri- teria can be found in [2, 8, 9]. Regarding OFDM based advanced waveform candidates, filtered OFDM (f-OFDM) schemes are receiving considerable attention due to their ability to address the mentioned issues while maintaining a high level of commonality with legacy OFDM systems [10, 11]. Specifically, the system bandwidth is divided into arbitrary num- bers of subbands, each containing a legacy OFDM signal. Consequently, f-OFDM is capable of retaining the advantages of OFDM while avoiding its limitations. First, filtering is applied to every single subband to suppress out-of-band (OOB) emissions; thus the guard band can be reduced with a better localized spectrum. Second, numerology can be optimized inde- pendently for a certain type of service within each subband; thus services with different technical requirements are flexibly supported. Third, thanks to the filtering, the synchro- nization requirement is also relaxed due to the reduced sidelobe, making interference from asynchronous transmissions more tolerable. Many aspects of f-OFDM, such as general framework and methodology, design and implementation, and field trials, have been reported in literature [10-18].
