| Abstract: | This paper proposes a two-dimensional(2-D) projection algorithm by which filter coefficients can be updated both along the horizontal and the vertical directions on a 2-D plane.Some basic properties of the algorithm are derived. In order to compare with other 2-D adaptive algorithms,it is applied to the identification of 2-D systems with stationary or non-stationary characteristics. Simulation results show that the proposed 2-D Modified Projection Algorithm(MPA) achieves good performance. |
