The invention relates to a method for estimating the impulse response h(t) of a cable network by means of myopic deconvolution. According to the invention, a test signal s(t) is introduced at an input point of the network and a signal y(t) is measured at an output point of the network, said input and output points preferably being the same. The method includes a step (300) comprising an initial estimation of the impulse response h(t) by means of deconvolution of signal y(t) with a kernel corresponding to the test signal s(t) and a step (301) comprising the estimation of a deconvolution kernel g(t) using the result of the initial estimation of the impulse response h(t), said kernel taking account of the distortions ?(t) introduced by the network. The method also includes a step (203) comprising the refined estimation of h(t) by means of deconvolution using kernel g(t). |
