摘要：

Based on the theory that new signals can be generated from a linear system with an input signal, the unified clasiffication methods for both determinated nonstationary signals and random nonstationary signals are deeply studied, including the linear time-varying system method described by the Green function; the self-exitational oscillation sinusoidal method based on the boundary stable linear system excited by a modulation function; the linear system combination method for the linear time invariant system and the boundary stable and unstable systems with random input signals. With the advantages of universality and systematism, such classification method is convenient for the unified study to both determinate nonstationary signals and random nonstationary signals. ©, 2015, Tongxin Xuebao/Journal on Communications.
