Researchers have developed a compact, low-cost convolutional spectrometer that delivers lab-grade precision for applications ...
Exercise 1. Let $${ n = 1, 2, \dots }$$ be such that $${ f_n \in A(\mathbf{T}) }$$ and $${ ||f_n||_{A(\mathbf{T})} \le 1 }$$. Assume that $${ f_n }$$ converges ...
Abstract: Blind modulation classification (BMC) is a key technology for communication perception intelligence, cognitive radio, and electronic countermeasures. With the wide applications of orthogonal ...
Abstract: Digital signal and image processing using reduced biquaternions (RBs) are introduced in this paper. RBs are an extension of the complex numbers, following the doubling procedure. Two useful ...
A differentiable fractional Fourier transform (FRFT) implementation with layers that can be trained end-to-end with the rest of the network. This package provides implementations of both fast ...
College of Information and Communication Engineering, Harbin Engineering University, Harbin, China. MTI band-stop filter as a “single channel”, followed by detection is relatively simple. When the ...
At the same time, we need to think carefully about how to use them and how to prevent their misuse. I oppose recent suggestions that we simply ban their development, but I support and participate in ...
To address this issue, this paper proposes a Multi-Scale Frequency Convolution (MSFC) module, which constructs convolution kernels with different receptive fields in the frequency domain to achieve ...
