Topological Signal Processing Over Simplicial Complexes [PDF]
IEEE Transactions on Signal Processing, 2019 The goal of this paper is to establish the fundamental tools to analyze signals defined over a topological space, i.e. a set of points along with a set of neighborhood relations.

EURASIP Journal on Advances in Signal Processing, 2023 Sampling and reconstruction play a critical role in signal processing. The non-ideal sampling conditions motivate the development of the sampling theory. In this paper, associated with multiple non-ideal conditions, we discuss the nonuniform sampling and

Introducing Hypergraph Signal Processing: Theoretical Foundation and Practical Applications [PDF]
IEEE Internet of Things Journal, 2019 Signal processing over graphs has recently attracted significant attention for dealing with the structured data. Normal graphs, however, only model pairwise relationships between nodes and are not effective in representing and capturing some high-order ...

Известия высших учебных заведений России: Радиоэлектроника, 2021 Introduction. The digital representation of received radar signals has provided a wide range of opportunities for their processing. However, the used hardware and software impose some limits on the number of bits and sampling rate of the signal at all ...

Ranging Property of the Dual-Band Band Limited Signal (DBBLS)
Advances in Electrical and Computer Engineering, 2012 The Dual-Band Band Limited Signal (DBBLS) is a signal with its power spectral density consisting of two separate lobes. Signals that can be considered as DBBLS are for example signals with BOC, AltBOC modulation, signals modulated on two close carriers

Demodulating BOC signals using compressive signal processing
Dianzi Jishu Yingyong, 2019 In order to lower the sampling frequency of binary offset carrier(BOC) signal, a BOC signal demodulation scheme based on compressive signal processing is proposed.

Experimental Study on Sampling Theorem in Signal Processing
Journal La Multiapp, 2021 This practicum is to define the study properties of the sampling theorem. Understand the effect of selecting the sample size and its effect on the signal recovery process. The experiment utilizes a computer or portable workstation to run an examination of the hypothesis reenactment program. From the test information gotten, it can be concluded that the

Near-Optimal Graph Signal Sampling by Pareto Optimization
Sensors, 2021 In this paper, we focus on the bandlimited graph signal sampling problem. To sample graph signals, we need to find small-sized subset of nodes with the minimal optimal reconstruction error.
