OFDM Versus Filter Bank Multicarrier

Abstract

Behrouz Farhang-Boroujeny ] [ Development of broadband communication systems ]s of today, orthogonal frequency division multiplexing (OFDM) has been the dominant technology for broadband multicarrier com munications. However, in certain applications such as cognitive radios and uplink of multiuser multicarrier systems, where a subset of subcarriers is allocated to each user, OFDM may be an undesirable solution. In this article, we address the shortcomings of OFDM in these and other applications and show that filter bank multicarrier (FBMC) could be a more effective solution. Although FBMC methods have been studied by a number of researchers, and some even before the invention of OFDM, only recently has FBMC been seriously considered by a few standard committees. The goal of this article is to bring this upcoming trend to the attention of the signal processing and communications communities and to motivate more research in this important area.

5G – Wireless Communications for 2020

“…• FBMC (Filter Bank Multicarrier) [55], defines a waveform where every symbol transmitted in each subcarrier passes through a specifically designed filter. OFDM can be seen as an FBMC system, where the selected filter is the rectangular window in the time domain.…”

Analysis of the interference from GFDM to OFDM signals in same band

“…FBMC (Filter Bank Multicarrier) [1], UFMC (Universal Filtered Multicarrier) [2], GFDM (Generalized Frequency Multicarrier Multiplexing) [3,4] and so on are examples of these so called "New Waveforms". Since these schemes have less OOB (out-of-band) emissions in general, more efficient spectrum usage is expected.…”

Development of Wireless Access and Flexible Networking Technologies for 5G Cellular Systems

“…The first one is massive multiple-input multiple-output (MIMO) technologies [19]- [21] for further enhancement of spatial spectral efficiency, as well as for its application to beamforming/beamtracking to achieve higher user rate. Moreover, waveform shaping techniques that suppresses out-of-band radiation like filter bank multi carrier (FBMC) technique [22] and sparse code multiple access (SCMA) [23] is also developed for flexible multiple access for massive connection IoT.…”
