摘要：

It is reported that signal encoding with high-dimensional chaos produced by delayed feedback systems with strong nonlinearity can be broken. The procedure is described and the method is illustrated with chaotic waveforms obtained from a strongly nonlinear optical system used by the authors previously to demonstrate signal encryption and decryption with wavelength chaos. The method can be extended to an systems ruled by nonlinear time-delayed differential equations. (C) 2003 MAIK "Nauka/Interperiodica".
