In the domain of Spoken Language Understanding (SLU) the primary objective is to extract important information from audio commands, like the intent of what a user wants the system to do and specific entities like locations or numbers. This paper presents a simple method that integrates intents and entities into a beam search algorithm, and, in combination with a general-purpose Speech-to-Text model, enables the creation of customized SLU-decoders without any additional training. Constructing such decoders is very fast and only takes a few seconds. It is also completely language-independent. In comparative assessments across multiple benchmarks, this method demonstrates comparable performance to several other SLU strategies, while significantly surpassing them in terms of computational speed.

To increase the efficiency of digital telecommunication systems using signals with orthogonal multiplexing, a new approach is proposed based on the use of orthogonal multi-point Hartley-Gabor signaling bases with good frequency-temporary localization. The advantages of this approach in comparison with the known ones are substantiated. It is shown that the proposed multi-window bases have the property of invariance to the action of a group of frequency-time shifts. This made it possible to develop an effective operator method for their orthogonalization, which turned out to be much simpler than the well-known matrix algebraic method. To construct a computational orthogonalization algorithm, a new spectral apparatus in the form of the Hartley-Zak orthogonal transform has been developed, which is consistent with the group of frequency-time shifts and is of independent practical interest. Strict analytical expressions describing the entire algorithm for the synthesis of the Hartley-Gabor orthonormal basis are given, and the possibility of its fast computational implementation is substantiated. The results of a computational experiment confirming a good time-frequency localization of the basis functions are presented.

This simulation study aims to compare the physical layer performance of the 5th Generation (5G) New Radio Non-Terrestrial Networks (NR NTN) air interface with Digital Video Broadcasting (DVB) technologies, specifically analyzing the Second Generation Satellite Extensions (S2X) standard on the Downlink (DL) and DVB- Return Channel via Satellite 2nd generation (RCS2) standard on the Uplink (UL). The study assumes a reference geosynchronous satellite telecommunication system operating in the Ka-band frequencies. The comparison analysis of the physical layers demodulation performance on the Forward (FWD) link reveals an average spectral efficiency decrease from 15 to 26% for NR PDSCH (Physical Downlink Shared Channel) in comparison to DVB-S2X. The analysis of the Return (RTN) link indicates comparable performance between NR PUSCH (Physical Uplink Shared Channel) and DVB-RCS2, with a marginal advantage for either technology based on specific study cases. The conclusions drawn from the performance comparison emphasize the potential for optimizing NR waveform configuration to improve spectral efficiency and reduce implementation losses through enhanced channel estimation and phase tracking algorithms. Moreover, this study outcome advocates for the completion of the physical layer comparison with System Level simulations of both technologies. This would make it possible to consider additional implications such as nonlinear amplification effects, control plane overhead, and scheduling efficiency.

Rate splitting multiple access (RSMA) and reconfigurable intelligent surface (RIS) are two prospective technologies for improving the spectral and energy efficiency in future wireless communication systems. In this work, we investigate a rate splitting (RS) technique for an RIS-aided system in the presence of only statistical channel knowledge. We propose an algorithm with a quasi closed-form solution based only on the second-order channel statistics, which reduces the design complexity of the system as it does not require estimation of the channel state information (CSI) and optimisation of the precoding filters and phase shifts of the RIS in every channel coherence interval.

Representing variable-length and continuous-indexed signals through a linear combination of basis functions poses a fundamental challenge in science and engineering. Current approaches resort to preprocessing steps, such as interpolation and extrapolation, to handle irregular and off-grid measurements, which compromise the physical nature of signals and degrade the representation performance. To address this challenge, rather than utilizing discrete vectors, we introduce a Bayesian functional representation model that capitalizes on the continuous nature and rich expressiveness of Gaussian processes to facilitate interpretable and effective basis function learning. Moreover, an analytical and efficient algorithm based on the variational inference framework is developed. Experimental results using real-life datasets demonstrate the superior performance of our proposed method.

Audio deepfake detection (ADD) aims to verify the authenticity of audio. However, its performance declines sharply when facing significant domain discrepancies caused by unknown datasets. Unsupervised domain adaptation (UDA) has been applied to mitigate domain mismatch. However, as generative models evolve, existing UDA methods struggle with catastrophic forgetting when facing continuously emerging spoofing methods. To address this challenge, we introduce continual UDA for ADD, which involves sequentially training across multiple target domains with continual learning. We propose a causality-distillation-based continual domain adversarial training framework for continual UDA, called CD-DAT. Specifically, we employ the domain adversarial training (DAT) framework to learn both spoofing-discriminative and domain-invariant deep features. In addition, we design a continual learning algorithm utilizing causality distillation to capture the mapping between utterances and classes, effectively mitigating forgetting and maintaining generalization. Experiments demonstrated that CD-DAT improved detection performance across all domains, confirming its memory stability and learning plasticity.

Quantum networks are an actively researched and promising field, aiming to achieve efficient quantum information transmission by interconnecting quantum nodes. In large-scale quantum networks, end-to-end throughput is a critical factor that affects the overall performance of the network. The maximum flow problem, extensively studied in classical network theory, identifies a set of paths between the source and destination nodes that maximizes the total flow. This study extends the maximum flow problem to quantum networks, focusing on coordinating multiple paths for multi-path quantum communication. We propose a Quantum Multi-Path Communication Protocol (QMCP) that employs maximum flow theory to allocate transmission resources across multiple nodes efficiently, thus maximizing the total transmission capacity from the source to the destination. Our evaluation demonstrates that QMCP significantly enhances end-to-end throughput in quantum networks.

The earbud-based ballistocardiogram (BCG) assessment holds significant promise for monitoring diverse physiological signals, including stress, cardiac activity, and blood pressure. However, unlike traditional methods that measure the force component along the head-to-foot axis for enhanced BCG signal quality, ear-worn devices are prone to orientation misalignment, leading to significant variations in BCG morphology. To address this challenge, we propose two novel algorithms: one that employs sensor-to-body-segment calibration and another that applies a calibration-free, physiologically informed axis fusion method to enhance earbud-based BCG signal assessment. We evaluate the performance of these approaches against existing methods, focusing on heart rate variability (HRV) estimation and morphological feature extraction. Through a comprehensive investigation, we aim to identify optimal strategies for obtaining high-quality BCG signals using ear-worn devices.

Clustered federated learning (FL), which groups clients with similar data distributions for collaborative training, represents a pivotal technique within federated learning for effectively addressing the challenges posed by non-IID data on clients. Existing clustered FL algorithms typically endeavor to learn distribution similarities of clients iteratively or indirectly through representations like gradients and loss. This necessitates resource-intensive pre-training or multiple iterations to attain stable clusters, thereby incurring additional communication cost and computational overhead. To address the above issues, we propose lightweight Clustered Federated Learning via Feature Extraction (FECFL). FECFL adopts a simple but effective client representation, i.e., the features extracted from the clients’ data using identically initialized models without any pre-training, to perform efficient one-shot clustering. Moreover, client data distribution is often dynamic in practice. To tackle distribution shift, we embed a distribution monitoring mechanism in FECFL, enabling adaptive re-grouping for new distributions. Finally, we demonstrate the benefits of FECFL over the baselines by conducting experiments on various datasets and distributions.

This article describes the development of an algorithm for increasing the accuracy of measuring the frequency and bandwidth of a signal in conditions of limited digital technology resources and time constraints. The purpose of the study was to apply the short-length FFT and CORDIC algorithms together. To do this, an algorithm was developed and tested on Xilinx FPGAs. As a result, an algorithm was obtained that can be used in systems where it is not possible to implement a long-length FFT, but high accuracy is required.
