—In this paper, a two-dimensional (2-D) version of
the recently proposed second order Recursive Inverse (2nd
order RI) algorithm is introduced. In the proposed algorithm,
instead of estimating the inverse autocorrelation matrix, a
second order estimate of the autocorrelation matrix and cross
correlation vector, which provide an improved and a more
stable performance, are used. Also, the filter coefficients are
updated along both the horizontal and vertical directions on a
2-D plane. The performance of the proposed algorithm is
compared to that of the 2-D RLS algorithm in Adaptive Line
Enhancer (ALE) problem. Simulation results show that the
proposed algorithm leads to an improved performance
compared to that of the 2-D RLS algorithm.
