We address the problem of estimating blindly a linearly modulated sequence of unknown rate transmitted over an unknown frequency selective channel. We achieve the goal by extending the concept of deconvolution to a cyclo-stationary context and present a generic class of functionals, the minimization of which achieves the equalization. This defines estimates of the symbol rate: by construction, they are insensitive to a lack of excess bandwidth, bestowing a clear advantage on them over the estimates of the literature.
