A Novel Linear Filter for Incremental Delta-Sigma ADC Based on Modified Least Squares Algorithm
Circuits, Systems, and Signal Processing - - 2024
Wang Yuqi, Wang Haiyong
This paper introduces a novel algorithm for optimizing the coefficients of the digital filters used in incremental delta-sigma analog-to-digital converters (IDSC). This algorithm is modified from constrained linear least squares (LS) to improve the signal-to-noise-and-distortion ratio (SNDR) of IDSC and minimize the oversampling rate (OSR) of the modulator, which enhances system speed and reduces ...... hiện toàn bộ
Parameter Identification Methods for an Additive Nonlinear System
Circuits, Systems, and Signal Processing - Tập 33 - Trang 3053-3064 - 2014
Jing Chen, Yunxia Ni
This paper deals with parameter identification methods for an additive nonlinear system with a preload nonlinearity and a piece-wise nonlinearity. By using a switching function, we transfer the model of the additive nonlinear system into an identification model, and propose a recursive least squares algorithm and two modified stochastic gradient (SG) algorithms to estimate the parameters of the id...... hiện toàn bộ
Analysis of Noise Immunity for Wide OR Footless Domino Circuit Using Keeper Controlling Network
Circuits, Systems, and Signal Processing - Tập 37 - Trang 4599-4616 - 2018
Amit Kumar Pandey, Pawan Kumar Verma, Rajesh Verma, Tarun Kumar Gupta
Due to high-speed and low area, domino circuits are used in a variety of applications such as comparator, adder, MUX, memory, microprocessor, and adder. In this paper, we propose a keeper controlling network to improve the noise immunity and performance for wide fan-in OR footless domino circuit. In the proposed design, the keeper controlling network controls the keeper transistor. The network its...... hiện toàn bộ

Genetic Watermarking for Zerotree-Based Applications
Circuits, Systems, and Signal Processing - Tập 27 - Trang 171-182 - 2008
Shu-Chuan Chu, Hsiang-Cheh Huang, Yan Shi, Ssu-Yi Wu, Chin-Shiuh Shieh
An optimized scheme for watermarking based on zerotrees is proposed in this paper. Digital watermarking is an effective means for protecting copyrights with three of the most fundamental requirements: watermark imperceptibility, watermark robustness, and watermark capacity. Conventional techniques in the literature mainly perform watermark embedding and extraction processes in the transform domain...... hiện toàn bộ
Nonplanar switchable arrays
Circuits, Systems, and Signal Processing - - 1988
J. L. Aravena, W. A. Porter
On-line signal processing and automatic control applications give rise to numerous examples of computationally intense algorithms. Architectures which are algorithmically specialized and provide massive parallelism are necessary to cope with such computational requirements. Systolic arrays, which feature parallelism, local communications, and VLSI compatability appear to match up well with these c...... hiện toàn bộ
Multiple-Parameter Radar Signal Sorting Using Support Vector Clustering and Similitude Entropy Index
Circuits, Systems, and Signal Processing - Tập 33 - Trang 1985-1996 - 2013
Zhanling Wang, Dengfu Zhang, Duyan Bi, Shiqiang Wang
The radar signal sorting method based on traditional support vector clustering (SVC) algorithm takes a high time complexity, and the traditional validity index cannot efficiently indicate the best sorting result. Aiming at solving the problem, we study a new sorting method based on cone cluster labeling (CCL) method. The CCL method relies on the theory of approximate coverings both in feature spac...... hiện toàn bộ
Least Squares Identification for Hammerstein Multi-input Multi-output Systems Based on the Key-Term Separation Technique
Circuits, Systems, and Signal Processing - Tập 35 - Trang 3745-3758 - 2015
Qianyan Shen, Feng Ding
System modeling and parameter estimation are basic for system analysis and controller design. This paper considers the parameter identification problem of a Hammerstein multi-input multi-output (H-MIMO) system. In order to avoid the product terms in the identification model, we derive a pseudo-linear identification model of the H-MIMO system through separating a key term from the output equation o...... hiện toàn bộ
Maximum Correntropy Criterion for Robust TOA-Based Localization in NLOS Environments
Circuits, Systems, and Signal Processing - Tập 40 - Trang 6325-6339 - 2021
Wenxin Xiong, Christian Schindelhauer, Hing Cheung So, Zhi Wang
We investigate the problem of time-of-arrival (TOA)-based localization under possible non-line-of-sight (NLOS) propagation conditions. To robustify the squared-range-based location estimator, we follow the maximum correntropy criterion, essentially the Welsch M-estimator with a redescending influence function which behaves like ...... hiện toàn bộ
