This paper presents an iterative detector that, by thresholding the output of the matched filter, gives maximum-likelihood sequence detector (MLSD) decisions on binary, antipodally modulated symbols that have been corrupted by intersymbol interference and additive Gaussian noise. The detector will make decisions on some, but often not all, of the symbols in a transmitted sequence, and those dec...
This paper handles the problem of detecting signals with known form and structure and unknown or random amplitude and phase in the presence of compound-Gaussian noise with known spectral density in remote sensing systems. The generalized detector (GA) based on the generalized approach to signal processing (GASP) in noise is investigated in [1]–[5]. The structure of the GA detector is independen...
PURPOSE The primary aim of this study is to investigate the potential benefit of the Teager-Kaiser Energy Operator (TKEO) as data pre-processor, in an autonomous burst detection method to classify electromyographic signals of the (fore)arm and hand. For this purpose, optimal settings of the burst detector, leading to minimal detection errors, need to be known. Additionally, the burst detector i...
In this paper, we consider the problem of cooperative spectrum sensing in the presence of the noise power uncertainty. We propose a new spectrum sensing method based on the fuzzy hypothesis test (FHT) that utilizes membership functions as hypotheses for the modeling and analyzing such uncertainty. In particular, we apply the Neyman–Pearson lemma on the FHT and propose a threshold-based local de...
Audiograms measured with a high frequency resolution often show quasi-periodic ripples of up to 15 dB in normal-hearing listeners. This fine structure of the threshold in quiet is commonly associated with the active processes in the cochlea. Therefore its absence is discussed in the literature as an indicator of cochlear vulnerability. In order to enable a quick detection and an objective quant...
For the (coherent) small-angle X-ray scattering (SAXS) beamline X12SA of the Swiss Light Source at the Paul Scherrer Institut, a novel X-ray detector is built, the PILATUS 2M. Contributions in module fabrication, detector assembly, characterization and calibration are covered within the framework of this thesis. Furthermore, data analysis of a particular SAXS experiment demonstrating the perfor...
