Blind deconvolution of system with unknown response excited by cyclostationary impulses

The problem of determining the unknown responses of a system which is continuously excited by cyclostationary signals is considered. By exploiting the periodicity of the input impulses, an approach based on array signal processing techniques is proposed to estimate the system responses. This method generalizes Bresler´s (1989) idea of resolving overlapping echoes by partitioning the signals into portions which fit the mathematical formulation used by Bresler. A compensating algorithm is also devised to compensate the random uncertainties and perturbations of the system and the signals. Once the system responses are determined, standard methods can be used to find the positions and amplitudes of the impulses. Prospective and promising simulation results are obtained
