该文利用局部正交约束，采用反向投影策略，提出一种基于算子的信号自适应分解方法。该方法将输入信号建模为多个基本信号和一个残差信号之和，并且基本信号落在所定义算子的零空间中。通过仿真和实际信号的实验，展示了所提算法对于解决信号处理中的模式混叠问题的可行性，有效性和实用性。

An operator-based approach for adaptive signal separation is proposed by using the locally orthogonal constraint and adopting back projection strategy. The approach adaptively separates a signal into additive subcomponents and a residual signal, where the subcomponents are in the null space of the operators. Experiments, including simulated signals and a real-life signal, demonstrate the feasibility, efficiency, and practicability of the proposed approach for solving the mode mixing phenomenon.
