Block Adaptive Filter With Time-Domain Update Using Three Transforms

Madihally J. Narasimha IEEE Signal Processing Letters, 2007

Implementation of real signal block adaptive filters with time-domain update using three fast Fourier transforms (FFTs) is delineated. The reduction from five to three FFTs is achieved by combining the required convolution and correlation operations into a single complex filtering process. The proposed method requires fewer additions than the conventional five FFT solution. It also has a more elegant architecture ...

In this paper we present a new algorithm for accelerating the potential calculation which occurs in the inner loop of iterative algorithms for solving electromagnetic boundary integral equations. Such integral equations arise, for example, in the extraction of coupling capacitances in three-dimensional (3-D) geometries. We present extensive experimental comparisons with the capacitance extraction code FASTCAP and demonstrate that, for a ...


The Optimization of Spectrum Analysis for Signal Harmonics

T. P. Tsao; R. C. Wu; C. C. Ning IEEE Power Engineering Review, 2001

FFT has been widely applied to the technology of spectrum analysis. However, since the signal sampling is random and FFT has specific limitations, some infections have inevitably been created. The picket-fence effect and the leakage effect are common phenomena. This paper explores the optimization of spectrum analysis for signal harmonics. By means of scale fine-tuning, the frequency scales will match ...

  • POWER QUALITY ANALYSIS

    Modern power grid can have a large penetration of distributed generation (DG) at the distribution level. One of the most important standards related to the interconnection of DG into the electrical distribution system is the IEEE 1547. This chapter discusses simulation tools for modeling fundamentals of power quality performance assessment. Power quality indices concern the electrical interaction between the main network and their customers. It can be decoupled in two main issues addressed in the chapter: the voltage quality concerns the way in which the supply voltage affects equipment, and the current quality concerns the way in which the equipment current affects the system. Power quality variations are classified as either transient or steady???state disturbances. The power factor is strongly influenced by the harmonic content of the voltage and current. MATLAB has built???in functions to calculate the discrete Fourier transform (DFT) or fast Fourier transform (FFT) and the corresponding inverses.

  • FFT-Based Terrain Segmentation for Underwater Mapping

    A method for segmenting three-dimensional scans of underwater unstructured terrains is presented. Individual terrain scans are represented as an elevation map and analysed using fast Fourier transform (FFT). The segmentation of the ground surface is performed in the frequency domain. The lower frequency components represent the slower varying undulations of the underlying ground whose segmentation is similar to de-noising / low pass filtering. The cut-off frequency, below which ground frequency components are selected, is automatically determined using peak detection. The user can specify a maximum admissible size of objects (relative to the extent of the scan) to drive the automatic detection of the cut-off frequency. The points above the estimated ground surface are clustered via standard proximity clustering to form object segments. The approach is evaluated using ground truth hand labelled data. It is also evaluated for registration error when the segments are fed as features to an alignment algorithm. In both sets of experiments, the approach is compared to three other segmentation techniques. The results show that the approach is applicable to a range of different terrains and is able to generate features useful for navigation.
