    This article focuses on problems and issues related to PQ and power system diagnostics, in particular those where signal processing techniques are extremely important. PQ is a general term that describes the quality of voltage and current waveforms. PQ problems include all electric power problems or disturbances in the supply system that prevent end-user equipment from operating properly. View full abstract»

    In this article, we have surveyed the main needs for signal processing development and argued for a sensor fusion approach where all tasks are considered jointly. First, the section "automotive safety systems" summarized a number of safety systems, and it was pointed out that a limited number of sensors can be sufficient to implement a variety of safety systems. Second, the active development of i... View full abstract»

    The need for low-complexity devices with low-power consumption motivates the application of suboptimal noncoherent ultra-wideband (UWB) receivers. This article provides an overview of the state of the art of recent research activities in this field. It introduces energy detection and autocorrelation receiver front ends with a focus on architectures that perform the initial signal processing tasks ... View full abstract»

    Spoken language user interfaces can dramatically speed up computer use. Unfortunately, if the speech user interface interferes too often, the user turns it off. Users are unforgiving: a technology that impairs productivity just once may never get a second chance. To give the user interface a fighting chance, why not endow it with a certain amount of emotional sensitivity? Users respond better to a... View full abstract»

    Speech sounds are encoded by time-varying spectral patterns called acoustic cues. The processing and detection of these acoustic cues lead to events defined as the psychological correlates of the acoustic cues. Due to the similarity between the acoustic cues, speech sounds form natural confusion groups. When the feature of the sound within a group is masked by noise, one event can turn into anothe...

    We describe the use of splines for solving nonlinear model estimation problems, in which nonlinear functions with unknown shapes and values are involved, by converting the nonlinear estimation problems into linear ones at a higher- dimensional space. This contrasts with the typical use of the splines for function interpolation where the functional values at some input points are given and the valu... View full abstract»

    This article presents a simple way to construct a pair of quasi-linear-phase bandpass filters that have identical magnitude responses and differ in phase by 90deg that can be used for analytic signal generation. Furthermore, these filters have useful symmetry properties that significantly reduce their computational complexity and coefficient storage requirements, and there is no inherent length li...
