  • 摘要: 該文利用局部正交約束，采用反向投影策略，提出一種基于算子的信號自適應(yīng)分解方法。該方法將輸入信號建模為多個基本信號和一個殘差信號之和，并且基本信號落在所定義算子的零空間中。通過仿真和實際信號的實驗，展示了所提算法對于解決信號處理中的模式混疊問題的可行性，有效性和實用性。
    Abstract: 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.
