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

Cycle slips strongly impact the performance of phase tracking algorithm leading, in the worst case, to a permanent loss of lock of the signal. In this paper, we propose a new nonlinear phase estimator to obtain more robust tracks. The latter stems fr

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

For a precise GNSS (Global Navigation Satellite System) positioning, carrier phase measurements are required. However, cycle slipping in classical phase locked loop (PLL) can lead to a local or permanent loss of lock. To address this problem, we prop

This paper investigates clutter rejection techniques in an OFDM symbol-based radar receiver. Two rejection filters that assume known the clutter covariance matrix are proposed. These aim at mitigating not only the clutter main peak but also its noise

The problem considered is that of estimating unambiguously migrating targets observed with a wideband radar. We extend a previously described sparse Bayesian algorithm to the presence of diffuse clutter and off-grid targets. A hybrid-Gibbs sampler is
