Abstract-Filter bank multicarrier (FBMC) has become a promising candidate to replace conventional orthogonal frequency-division multiplexing (OFDM) scheme in 5G technology due to its better spectral confinement which results in a reduced inter-channel interference (ICI). However, the viability of using FBMC in visible light communication has not been verified. In this work we present the first experimental validation of the DC-biased optical filter bank multicarrier (DCO-FBMC) modulation scheme over a free-space optical channel. Under different receiving powers, up to three times bit error rate performance improvement has been achieved using DCO-FBMC with different overlapping factors compared to that of conventional DCO-OFDM.

“…In that sense, one of the interesting features of polyphase structures is the exploitation of the cyclic nature of the IDFT/DFT exponentials, which leads us to introduce the modulo operation in the generated signal sample index in (11). Since any integer m can always be expressed as m = mod(m, P t ) + m P t P t , we can rewrite (11) as follows:…”

“…It is worthwhile mentioning that although the schemes obtained in transmission and reception are symmetrical, the methodology followed for their derivation has been slightly different. For example, the DFT operation in the reception schemes cannot be explicitly inferred from the signal model in (3) because the exponential term cannot be decoupled from the convolution operation as it was done in (11). Additionally, the final receiver architectures are obtained through the decomposition of the index of the convolution operation rather than the index of the output samples.…”

“…From a digital broadcasting perspective, MC signals are used in many standards such as the Digital Video Broadcasting (DVB-T [5], DVB-T2 [6], DVB-SH [7], and DVB-RCT [8]), Digital Audio Broadcasting (DAB) [9], and Digital Multimedia Broadcasting (DMB) [10], where orthogonal frequency-division multiplexing (OFDM) is the most widespread format of MC signaling adopted therein. In the recent years, though, there has been a growing interest in filter bank multicarrier (FBMC) signals as an alternative to conventional MC signaling based on OFDM [11]. Compared to the *Correspondence: jose.salcedo@uab.es Department of Telecommunication and Systems Engineering, Universitat Autònoma de Barcelona (UAB), Cerdanyola del Vallés, Barcelona 08193, Spain latter, FBMC can be understood as a generalized signaling scheme that allows the replacement of the rectangular shaping pulse by a band-limited one.…”

Multi-carrier (MC) signaling is currently in the forefront of a myriad of systems, either wired or wireless, due to its high spectral efficiency, simple equalization, and robustness in front of multipath and narrowband interference sources. Despite its widespread deployment, the design of efficient architectures for MC systems becomes a challenging task when adopting filter bank multi-carrier (FBMC) modulation due to the inclusion of band-limited shaping pulses into the signal model. The reason to employ these pulses is the numerous improvements they offer in terms of performance, such as providing higher spectral confinement and no frequency overlap between adjacent subcarriers. These attributes lead to a reduced out-of-band power emission and a higher effective throughput. The latter is indeed possible by removing the need of cyclic prefix, which is in charge of preserving orthogonality among subcarriers in conventional MC systems. Nevertheless, the potential benefits of FBMC modulations are often obscured when it comes to an implementation point of view. In order to circumvent this limitation, the present paper provides a unified framework to describe all FBMC signals in which both signal design and implementation criteria are explicitly combined. In addition to this, we introduce the concept of flexible FBMC signals that, unlike their traditional MC counterparts, do not impose restrictions on the signal parameters (i.e., symbol rate, carrier spacing, or sampling frequency). Moreover, our framework also proposes a methodology that overcomes the implementation issues that characterize FBMC systems and allows us to derive simple, efficient, and time-invariant transmitter and receiver architectures.

“…Later on the description of an OFDM/OQAM scheme using FFT and polyphase filtering [2] has paved the way to practical implementations. From a system viewpoint, various methods concerning channel estimation equalization and synchronization have been studied and simulated to demonstrate the potential of OFDM/OQAM in real transmission contexts [3]. Indeed, as the example of Coded OFDM (COFDM) for digital audio/video broadcasting (DAB, DVB) systems shows, a real-life demonstration often plays an essential role in the acceptance of a new technology [4].…”

This paper describes the OFDM/QAM and OFDM/OQAM platforms that have been built these last years in Orange Labs in order to compare both modulation schemes. The targeted application was related to the physical layer of mobile terrestrial digital video broadcasting networks; then system parameters are borrowed from the corresponding DVB standards. In addition to a usual evaluation on AWGN channel, SFN and TU channels with strong mobility have been emulated with our real-time hardware platforms. These platforms include realistic channel estimation/equalization and synchronization methods. Our results show that, for this mobile application, OFDM/OQAM can significantly outperform OFDM/QAM.
