Convolution is widely used as a linear and shift invariant (LSI) model for signal processing applications cite{vedantam2014discontinuous}. It has made countless contributions to filtering cite{stanković2010dynamic}, system identification cite{jankovic1994least}, time-series analysis cite{julier2005particle} and more recently denoising cite{moussa2011non}. In this paper, we focus on the textit{deconvolution} problem: Given a noisy observation corrupted by dynamic non-stationary textit{impulse} noise and a LSI model of a dynamic system, we show how to recover the original source signal using blind deconvolution techniques to estimate both the source signal and the dynamic noise pattern. We validate the method on simulated signals from the literature cite{sayed2014statistical,wang2014robust} used in previous deconvolution studies cite{souissi2014parallel,dang2012farfield}, and on real seismic data from cite{dang2012farfield} corrupted by man-made noise. In both cases, our deconvolution scheme is robust against impulse noise of varying duration and energy and proves to be able to recover the source signal with high fidelity even in the presence of powerful noise impulses.
% In this paper, we focus on deconvolution with impulse-noise. We treat each point of time separately as an independent noise sample. This allows to estimate each coefficient of the array using independent methods.
% We correct this error using both mean-squared-error estimation and blind deconvolution.

section{Introduction}
A convolution model $boldsymbol{x}[i] = boldsymbol{s}[i] * boldsymbol{h}[i]$ expresses each sample $boldsymbol{x}[i]$ of a dynamic discrete-time output signal $boldsymbol{x}$ as a linear combination of some input signal $boldsymbol{s}$ weighted by coefficients contained in $boldsymbol{h}$ and delayed by time $i$:
begin{equation}
boldsymbol{x}[i] = sum_{j = -infty}^{infty} boldsymbol{s}[j]boldsymbol{h}[i-j],
label{eq:convolution_model}
end{equation}
where convolution operator textbf{*} is defined as $f * g = sum_{k = - infty}^{infty} f[k]g[k-n]$. Under this model, it is possible to estimate either the source signal $boldsymbol{s}$ or the impulse response $boldsymbol{h}$ knowing one or the other by means of deconvolution.
In this paper, we focus on deconvolution from measurements corrupted by impulse noise. From here on forth, we consider a textbf{strictly causal} system where the impulse response $boldsymbol{h}[i]$ has all its coefficients equal to zero for times $i < 0$. This simplifies (eq.) eqref{eq:convolution_model} to:
begin{equation}
boldsymbol{x}[i] = sum_{j = 0}^{i} boldsymbol{s}[j]boldsymbol{h}[i-j].
end{equation}
We also assume that the system is given by $boldsymbol{h}[i]$ and that the output signal $boldsymbol{x}$ is distorted by a non-stationary textit{impulse noise} which modifies some samples of $boldsymbol{x}$ up to a scale factor:
begin{equation}
boldsymbol{x}_n[i] = boldsymbol{x}[i] * n[i],
label{eq:distorted_signal_model}
end{equation}
where $boldsymbol{n}$ is composed of individual impulses located at random time samples:
begin{equation}
n[i] = bigcup_{k in mathbb Z_+} n_k[i].
label{eq:impulse_noise_model}
end{equation}
where $mathbb Z_+$ is the set of positive integers. Each impulse $n_k[i]$ is localized at time sample $k$:
begin{equation*}
n_k[i] =
begin{cases}
varepsilon_k e^{ frac{(i-k)^2}{2sigma^2}}
& text{ for } i > k
\
0
& text{ otherwise }
end{cases},
label{eq:impulse_model}
end{equation*}
where $varepsilon_k$ is a normalization coefficient (defined below) that controls the energy content of each impulse, and multiplied by a textit{Gaussian window} which ensures that each impulse will have negligible energy outside some time interval around its peak centered at time sample $k$. Thus, as presented here, (eq.) eqref{eq:impulse_noise_model} has impulses non-zero only for time samples higher than their peak because of (eq.) eqref{eq:impulse_model}. Later on in this paper we will relax this condition by allowing each impulse to occur around its peak through time.
If $varepsilon_k$ tends towards one (infinite energy), then theoretically impulse noise leads to an error in all time samples higher than its peak. On the other hand, if $varepsilon_k$ tends towards zero (impulse noise degraded to a normal noise sample), then it doesn't cause any problems because then (eq.) eqref{eq:distorted_signal_model} collapses to (eq.) eqref{eq:convolution_model}.
The energy content of each impulse is proportional to $varepsilon_k$, but we want it to be normalized even if it tends towards one so that the sum of all impulse energies is always equal to one. To fix this issue, we need all impulses to have insufficient energy before being combined so that their energy remains close to zero before they are actually used in (eq.) eqref{eq:distorted_signal_model}. Thus we define $varepsilon_k$ as follows
begin{equation}
varepsilon_k = (1 - lambda_k) cdot
(frac{sum_{k' = k + 1}^{infty}lambda_{k'}}{sum_{k' geq k + 1}lambda_{k'}})^{-1},
