Abstract 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

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 time-frequency characteristics of the chann

Traditional synchronization techniques are usually challenged by Faster-than-Nyquist (FTN) signals which discard orthogonal pulses to the advantage of an increased spectral efficiency. In this paper, we studied data-aided timing estimation in FTN sce
In this paper, we examine the optimal power allocation of a multicarrier waveform for a dual-function radar-communication system. We derive an information theoretic optimization problem to enhance radar estimation while fulfilling a communication inf

Blind deconvolution (BD) is the recovery of a scene of interest convolved with an unknown impulse response function. Within a Bayesian context, prior distributions are assigned to both unknowns to regularize the BD problem. A common approach is to us

In this paper, we propose an extension of the so-called "symbol-based" multicarrier radar receiver to compensate range migration via an efficient coherent summation. Indeed, this situation is likely to happen in dual function radar communications sce

Faster-than-Nyquist (FTN) signaling is a promising strategy to achieve high spectral efficiency at fixed constellation size, notably over power-constrained channels. However, various traditional synchronization techniques cannot be reused in presence

In waveform sharing scenarios, various radar receivers have been developed for orthogonal frequency-division multiplexing (OFDM) signals. More general waveforms, such as pulse-shaped multicarrier modulations received little attention so far, despite

In this paper, the problem of target masking induced by sidelobes arising in an OFDM RadCom System is considered. To fully exploit the waveform structure and address practical scenarios, we propose to deal with the sidelobes in the subband domain via
