    Given the wealth of literature on the topic supported by solutions to practical problems, we would expect the bootstrap to be an off-the-shelf tool for signal processing problems as are maximum likelihood and least-squares methods. This is not the case, and we wonder why a signal processing practitioner would not resort to the bootstrap for inferential problems. We may attribute the situation to s... View full abstract»

    This article discusses some examples of jackknifing multitaper estimates of spectra, coherences, and frequency estimates. Examples include barometric pressure data, where spectrum with an extremely large range plus many narrow-band processes are seen. Analysis of dropped-call rates in cellular phone systems and their coherence with solar radio data illustrates further uses of the jackknife and som... View full abstract»

    In this article, we have derived tests based on the wild bootstrap that allow checking for differences between two irregular signals observed with additive noise where the latter consists of independent but not necessarily identically distributed random variables. The signals are first denoised by kernel estimates and then compared by looking at the integrated squared difference. The bound between... View full abstract»

    Multifractal analysis is becoming a standard statistical analysis technique. In signal processing, it mostly consists of estimating scaling exponents characterizing scale invariance properties. For practical purposes, confidence intervals in estimation and p values in hypothesis testing are of primary importance. In empirical multifractal analysis, the statistical performance of estimation or test... View full abstract»

    Using bootstrap local fitting to overcome parameteric regression problems. A common task in applying signal-processing methods to biological systems is estimating a transducer function. The particular system being analyzed may range from the very small, such as a retinal photoreceptor producing a voltage response on being stimulated with a flash of light, to the large and complex, such as a human ...

    This article is about the success story of a seemingly simple yet extremely powerful approach that has recently reached a celebrity status in statistical and engineering sciences. The hero of this story - bootstrap resampling - is relatively young, but the story itself is a familiar one within the scientific community: a mathematician or a statistician conceives and formulates a theory that is fir...

    This article provides an overview of nonlinear statistical signal processing based on the Bayesian paradigm. The next-generation processors are well founded on MC simulation-based sampling techniques. The development of the sequential Bayesian processor is reviewed using the state-space models. The popular bootstrap algorithm was outlined and applied to an ocean acoustic synthetic aperture towed a... View full abstract»

    Coming to the end of Part 1, we hope you have a different picture of a frame in your mind from a "picture frame." While necessarily colored by our personal bias, we intended this tutorial as a basic introduction to frames, geared primarily toward engineering students and those without extensive mathematical training. Frames are here to stay; as wavelet bases before them, they are becoming a standa... View full abstract»

    Synthetic aperture radar (SAR) allows the observation of the sea surface over large areas regardless of weather conditions. In what follows we discuss a digital signal processing (DSP) formalism that makes use of polynomial filters such as Volterra models to extract the geophysical information from SAR images and to model several nonlinear transfer functions. Polynomial filters allow the extension... View full abstract»

    Face-to-face communication conveys social context as well as words. It is this social signaling that allows new information to be smoothly integrated into a shared, group-wide understanding. Social signaling includes signals of interest, determination, friendliness, boredom, and other "attitudes" toward a social situation. Psychologists speculate that social signaling may have evolved as a way to ... View full abstract»

    This paper summarizes the neuroimaging methods in the diagnostic assessment process that have been applied to neuropsychiatric studies. Here, we outline the signal processing challenges in structural and functional neuroimaging methods and discuss the specific difficulties in multisite data analysis for the diagnosis of neuropsychiatric disorders. Currently, fMRI and other brain imaging methods ar... View full abstract»

    This lecture note presents a new method to capture and represent compressible signals at a rate significantly below the Nyquist rate. This method, called compressive sensing, employs nonadaptive linear projections that preserve the structure of the signal; the signal is then reconstructed from these projections using an optimization process.

    This article describes a novel complex oscillator, which is based on an interesting variation of the traditional CORDIC DDS and produces sine and cosine output samples of any specified angle. Our oscillator provides drastically improved phase noise performance (relative to a traditional CORDIC DDS) without the need for additional CORDIC iteration processing. In addition, our oscillator supports re... View full abstract»
