Effects of Multirate Systems on the Statistical Properties of Random Signals [PDF]

, 1993
In multirate digital signal processing, we often encounter time-varying linear systems such as decimators, interpolators, and modulators. In many applications, these building blocks are interconnected with linear filters to form more complicated systems.

Robust Inference for State-Space Models with Skewed Measurement Noise [PDF]

, 2015
Filtering and smoothing algorithms for linear discrete-time state-space models with skewed and heavy-tailed measurement noise are presented. The algorithms use a variational Bayes approximation of the posterior distribution of models that have normal ...

Improved Optical Signal Processing with On-Chip Programmable Filter

Photonics
Bandwidth-limited transmitters have become a severe issue with the rapid growth of bandwidth-hungry services. We investigate the impact of an on-chip optical pre-emphasizer on a bandwidth-limited transmitter and quantitatively analyze the results of ...

Large margin filtering for signal sequence labeling

, 2010
Signal Sequence Labeling consists in predicting a sequence of labels given an observed sequence of samples. A naive way is to filter the signal in order to reduce the noise and to apply a classification algorithm on the filtered samples.

Analysis and application of digital spectral warping in analog and mixed-signal testing [PDF]

, 2003
Spectral warping is a digital signal processing transform which shifts the frequencies contained within a signal along the frequency axis. The Fourier transform coefficients of a warped signal correspond to frequency-domain 'samples' of the original ...
