Summary
This study introduces a new framework for jamming pattern recognition (JPR) to identify known and unknown jamming signals in communication systems. The novel approach enhances communication robustness by accurately classifying diverse jamming patterns.
Area of Science:
- Electrical Engineering
- Signal Processing
- Artificial Intelligence
Background:
- Jamming patterns (JPs) pose a significant threat to modern communication systems, disrupting operations in civil and industrial applications.
- Accurate identification of known JPs and detection of unknown JPs are crucial for maintaining reliable communication links.
Purpose of the Study:
- To address the challenge of jamming pattern open set recognition (JP-OSR).
- To propose a novel framework that effectively identifies known JPs and detects unknown JPs in communication signals.
Main Methods:
- Utilized a Spiking Wavelet Transformer (SWT) for high-resolution time-frequency feature extraction.
- Employed Hyperspherical Maximum Class Separation (MCS) to align features and enhance inter-class distinctions.
- Integrated an energy-based model with an adaptive threshold to handle feature variability across different Jamming-to-Signal Ratios (JSR) and JPs.
Main Results:
- The proposed framework demonstrated superior performance in jamming pattern open set recognition (JP-OSR).
- The SWT effectively captured intricate temporal and spectral characteristics of jamming signals.
- The adaptive thresholding mechanism enabled accurate recognition of both known and unknown jamming types under varying JSR conditions.
Conclusions:
- The novel framework integrating SWT, MCS, and adaptive thresholding is effective for JP-OSR.
- The method offers a robust solution for improving the resilience of communication systems against jamming.
- Simulation experiments validated the superiority of the proposed approach for jamming pattern recognition.

9.3K
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze...

01:08IR Spectrum Peak Splitting: Symmetric vs Asymmetric Vibrations
1.2K
Identical bonds within a polyatomic group can stretch symmetrically (in-phase) or asymmetrically (out-of-phase). Similar to hydrogen bonding, these vibrations also influence the shape of the IR peak. Generally, asymmetric stretching frequencies are higher than symmetric stretching frequencies. For example, primary amines exhibit two distinct IR peaks between 3300–3500 cm−1 corresponding to the symmetric and asymmetric N-H stretching, while secondary amines exhibit a single...

01:23Propagation of Action Potentials
7.0K
The propagation of an action potential refers to the process by which a nerve impulse, or "action potential," travels along a neuron.
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...

01:17Energy and Power Signals
620
In an electrical system with a resistor, voltage and current signals facilitate the measurement of power and energy across the resistor. For a continuous-time signal, the total energy over a time interval is defined as the integral of the square of the signal's magnitude over that interval. Mathematically, this is expressed as:

01:41Signal Sequences and Sorting Receptors
6.1K
Signal sequences are short amino acid sequences that guide newly synthesized proteins to their proper location within the cell. Classical signal sequences are fifteen to sixty amino acids long and present at the N-terminus of a polypeptide chain. Each signal sequence has a conserved segment of basic residues towards their N terminus, a hydrophobic core, and a C-terminus rich in polar residues. The C-terminus also contains a signal cleavage site and features a -3 -1 sequence motif. The -3-1...

01:13¹H NMR Signal Multiplicity: Splitting Patterns
5.3K
When protons A and X are coupled, their nuclear spin energy levels are slightly modified. This is because the energy required to excite proton A to a spin state parallel to proton X is slightly different from the energy required for it to become anti-parallel to spin X. Consequently, there are two possible excitation frequencies for A (A1 and A2), depending on the spin state of X, and vice versa. The mutual nature of coupling implies that the difference between frequencies A1 and A2, indicated...
