    "abstract": "In this paper, a general model of wireless channels is established based on\nthe physics of wave propagation. Then the problems of inverse scattering and\nchannel prediction are formulated as nonlinear filtering problems. The\nsolutions to the nonlinear filtering problems are given in the form of dynamic\nevolution equations of the estimated quantities. Finally, examples are provided\nto illustrate the practical applications of the proposed theory.",
