Null Space Pursuit Algorithm Based on a Fourth-Order Differential Operator
The null space pursuit (NSP) algorithm based on a fourth-order differential operator is a method of signal processing. The NSP algorithm uses an adaptive operator to separate a signal into additive subcomponents. Furthermore, it is possible to design different operators to fit different signal models. In this paper, we propose a new type of a differential operator. We theoretically derive the new differential operator and then test the proposed method using simulated signals.
