Abstract :
In this paper, three new methods for two-dimensional (2-D) adaptive notch filter (ANF) are proposed. They not only contain similar and simpler structures but also can be derived by simpler adaptive algorithms compared with the previous ones. They are helpful for 2-D signal processing. Simulation results show that they can eliminate 2-D sinusoidal signals successfully.
