WaveComBox: a Matlab Toolbox for Communications using New Waveforms
share
Future generations of communications systems will target a very wide range of applications, with possibly very different specifications. This implies the need for a physical layer technology allowing for an ultra flexible allocation of the time-frequency resources. In this regard, the most popular modulation nowadays, namely, the orthogonal frequency division multiplexing (OFDM) modulation, is characterized by a very poor frequency localization, making frequency resource allocation much less flexible. In the light of these limitations, communications using new waveforms, relying on more sophisticated time windowing or filtering, have attracted a lot of attention for the last decade, such as offset-QAM-based filterbank multicarrier (FBMC-OQAM), universal filtered multicarrier (UFMC) or generalized frequency division multiplexing (GFDM). At the same time, the higher complexity of these new waveforms, not only in terms of implementation but especially conceptually, creates an entrance barrier that slow down their adoption by industries, standardization bodies and more generally in the telecommunication community. The WaveComBox toolbox, available at www.wavecombox.com, is a user-friendly, open-source and well documented piece of software aiming at simplifying the use and considerably lowering the entrance barrier of recently proposed waveforms. By using an abstract architecture, the toolbox allows for simple implementation of typical physical layer functionalities and for comparison with state-of-the-art technologies.
