Two dimensional adaptive filter using Laguerre function
A new two dimensional (2D) adaptive filter structure is developed. It is based on modeling the impulse response of the 2D IIR systems as a finite linear combination of a set of 2D Laguerre orthonormal functions. When it is required to identify a system with a long impulse response, computer simulation shows that the 2D Laguerre filter has a better performance than the conventional 2D FIR filter at the same computation cost.<<ETX>>
