It is based on the cascade of a linear FIR lter and a piecewise{linear interpolating function. Experimental results show a very good behaviour of the lter, which outperforms in many application examples the Sigma lter both in terms of visual quality and numerical results.

Recurrent Canonical Piecewise Linear Network and Its Application to Adaptive Equalization - Neural Networks, 1996., IEEE International Conference on
In this paper, we present a recurrent canonical piecewise linear (RCPL) network based on canonical piecewise-linear (CPL) function and autoregressive moving average model, and apply it to adaptive channel equalization. It, is shown that a recurrent neural network with piecewise linear activation function realizes an RCPL network. RCPL network has several advantages: First, i t can make use of s...
متن کاملCascade Adaptive Filters and Applications to Acoustic Echo Cancellation
Typical approaches to acoustic echo cancellation (AEC) in mobile telephones employ adaptive linear algorithms, such as the normalized least mean squares (NLMS) algorithm. Smaller, cheaper components on these devices introduce nonlinearities into the echo path, which adversely affect performance of linear AEC systems and necessitate means of nonlinear compensation. Memoryless nonlinear blocks th...
متن کاملAutoregressive Model with Partial Forgetting within Rao-Blackwellized Particle Filter
We are concerned with Bayesian identification and prediction of a nonlinear discrete stochastic process. The fact, that a nonlinear process can be approximated by a piecewise linear function advocates the use of adaptive linear models. We propose a linear regression model within a Rao-Blackwellized particle filter. The parameters of the linear model are adaptively estimated using a finite mixtu...
متن کاملBlock-oriented identification of Hammerstein/Wiener-models using the RLS-algorithm
A new method for identifying Hammerstein/Wiener models is proposed, where the parameters of a piecewise linear characteristic and a linear transfer function are estimated by recursive least-squares (RLS). Using smooth validity functions and an adaptive algorithm for optimal partitioning of the local linear models an efficient and accurate model can be identified.
متن کاملTemporal dynamics of the speech readiness potential, and its use in a neural decoder of speech-motor intention
We investigated the temporal dynamics of brain activity related to speech and motor preparation. Previous electroencephalography (EEG) studies of speech production have identified a slow wave negativity that occurs as early as 2 seconds prior to articulation, known as the readiness potential (RP). This EEG potential is commonly described as having two phases, an early slow component and a late ...
