DE LA ROSA VARGAS, José I. et al. A Comparative Evaluation of four Algorithms for Numeric Solution of the Deconvolution on Unidimensional Systems. Comp. y Sist. [online]. 2006, vol.10, n.2, pp.135-158. ISSN 2007-9737.

The present paper presents the comparison of a deconvolution algorithm with other three classical approaches for one-dimensional deconvolution of signals. The algorithm was proposed at the digital signal processing laboratory at UAZ. During the last three decades, the development of new ideas on the solution about deconvolution or n-dimensional signal restoration methods, have become to a new meaning to this problem, the idea remains the same since the 50's in the engineering literature, that is " signal restoration or approximation to it's original form with the purpose of a better analysis ". When a signal x(t) is generated, the only way to be picked up is by a sensor. During the sensing process the convolution of x(t) with another type of signals occurs. Then, a new signal is generated by the convolution of x(t) with a function h(t) and other noisy components. To obtain the original signal x(t), we have an inverse problem and the solution will deliver an estimation of x(t) or . The final purpose of this work is to evaluate and classify the signal restoration capacity of each method.
