FTN multicarrier transmission based on tight Gabor frames
A multicarrier signal can be synthesized thanks to a symbol sequence and a Gabor family (i.e., a regularly time–frequency shifted version of a generator pulse). In this article, we consider the case where the signaling density is increased such that inter-pulse interference is unavoidable. Over an additive white Gaussian noise channel, we show that the signal-to-interference-plus-noise ratio is...
متن کاملAnalysis of a FTN Multicarrier System: Interference Mitigation Based on Tight Gabor Frames
Cognitive radio applications require flexible waveforms to overcome challenges such as opportunistic spectrum allocation. In this context, filtered multicarrier modulations are particularly justified to fit timefrequency characteristics of the channel. In our theoretical framework, a multicarrier signal is described as a Gabor family the coefficients of which are the symbols to be transmitted a...
متن کاملDigital Gabor Filters Do Generate MRA-based Wavelet Tight Frames
Gabor frames, especially digital Gabor filters, have long been known as indispensable tools for local time-frequency analysis of discrete signals. With strong orientation selectivity, tensor products discrete (tight) Gabor frames also see their applications in image analysis and restoration. However, the lack of multi-scale structures existing in MRA-based wavelet (tight) frames makes discrete ...
متن کاملAnalysis of a Multicarrier Communication System Based on Overcomplete Gabor Frames
A multicarrier signal can be seen as a Gabor family whose coefficients are the symbols to be transmitted and whose generators are the time-frequency shifted pulse shapes to be used. In this article, we consider the case where the signaling density is increased such that interpulse interference is unavoidable. Such an interference is minimized when the Gabor family used is a tight frame. We show...
متن کاملCharacterization and computation of canonical tight windows for Gabor frames
Let (gna,mb)n,m∈Z be a Gabor frame for L (R) for given window g. We show that the window h0 = S− 1 2 g that generates the canonically associated tight Gabor frame minimizes ‖g − h‖ among all windows h generating a normalized tight Gabor frame. We present and prove versions of this result in the time domain, the frequency domain, the time-frequency domain, and the Zak transform domain, where in ...
