Discrete wavelet transform recursive inverse algorithm using second-order estimation of the autocorrelation matrix
The recursive least squares (RLS) algorithm was introduced as an alternative to least mean square (LMS) algorithm with enhanced performance. Computational complexity and instability in updating the autocolleltion matrix are some of the drawbacks of…

Image denosing in underwater acoustic noise using discrete wavelet transform with different noise level estimation
In many applications, Image de-noising and improvement represent essential processes in presence of colored noise such that in underwater. Power spectral density of the noise is changeable within a definite frequency range, and autocorrelation noise…
