Invited talk: FBMC: An Idea Whose Time Has Come

P. Siohan, Orange Lab, Rennes-France

In the famous paper: “Multicarrier modulation for data transmission: An idea whose time has come”, the author refers to conventional OFDM and also to multicarrier modulation based on offset (or staggered) QAM. Actually, in 1990 OFDM was already there with wireless (DAB) and wired (DSL) transmission systems and, since then, has known a tremendous success. At the contrary, all OFDM variants, today known as Filter Bank Multi-Carrier (FBMC) systems, are still marginal from a standardization and industrial point of view. However, with the OFDM/OQAM/IOTA proposal, the paper by Le Floch et al. in 1995 has renewed the interest for enhanced multicarrier systems. The talk will propose an overview of the impressive progresses that are being made since that time to get very competitive FBMC systems. Then, we will focus on some features of FBMC that still deserve a particular attention. Among those, are FBMC flexibility, packet transmission and efficient equalization.

Multicarrier modulation is enjoying great success in state-of-the-art physical layer wireless and wireline (e.g., power line communications) technologies. The most popular architecture is orthogonal frequency division multiplexing (OFDM). Aiming at increasing spectral efficiency, more general architectures based on filter bank modulation (FBM) have been proposed. This talk offers an overview of some recent advances and results about FBM trying to motivate the reasons why there is still space to devise interesting FBM digital architectures for application in multiple access asynchronous channels (both wireless and power line) affected by doubly dispersive fading and various non-idealities. In particular, focus will be given to Filtered Multitone Modulation (FMT) and novel schemes, namely, concatenated OFDM-FMT, MIMO Precoded FMT, Hybrid FMT, and Cyclic Block FMT. The application of such solutions is motivated by multiple ambitious objectives: the robustness not only to channel impairments but also to hardware limitations (FMT), the orthogonalization of the uplink channel (Concatenated FMT), the high capacity in MIMO frequency selective channels (Precoded FMT), the agile use of spectrum and the flexible adaptation of available resources (Hybrid FMT), the overall reduced latency/complexity and increased performance with  simple orthogonal filter bank design (Cyclic Block FMT).
The main features of such schemes will be described and illustrative examples of performance will be given.
