Abstract:
This paper addresses the harmonic retrieval problem in non-Gaussian ARMA noise. A hybrid ESPRIT approach using second- and third-order statistics is proposed. First, third-order statistics are used to identify the AR part of the non-Gaussian noise pr...

Abstract:
An LMS adaptive time delay estimation method with two windows is presented. This method can reduce the superfluous calculation greatly when the time of correlation is long. It is suitable for the time delay estimation of white band-limited random sig...

Abstract:
A new algorithm for the fast computation of a 2-D discrete cosine transform (DCT) is presented. It is shown that the N X N DCT, where N = 2m, can be computed using only N 1-D DCT's and additions, instead of using 2N 1-D DCT's, as in the conventional ...
