SURE-LET multichannel image denoising: undecimated wavelet thresholding
We propose an extension of the recently devised SURE-LET grayscale denoising approach for multichannel images. Assuming additive Gaussian white noise, the unknown linear parameter...

A DSP-based fuzzy system for real-time interference cancellation in DS-SS systems
This work demonstrates that high-end classical programmable digital signal processors (DSPs) can implement fuzzy systems for real-time communication processing. A systematic proce...

Quantifying EEG synchrony using copulas
In this paper, we consider the problem of quantifying synchrony between multiple simultaneously recorded electroencephalographic signals. These signals exhibit nonlinear dependenc...

Total-variation regularization with bound constraints
We present a new algorithm for bound-constrained totalvariation (TV) regularization that in comparison with its predecessors is simple, fast, and flexible. We use a splitting app...

Subspace-based DOA estimation using Fractional Lower Order statistics
Direction Of Arrival (DOA) estimation, using a sensor array, in the presence of non-Gaussian noise using Fractional Lower-Order Moments (FLOM)matrices is studied. In this paper, a...
