With the increasing sophistication of radar systems, jamming countermeasures have become more complex and variable. To effectively respond to complex and unknown threat signals, there is a need to enhance the intelligent capabilities of countermeasure systems. This paper proposes an intelligent optimization method for jamming strategies based on an improved Q-Learning algorithm. Through simulation experiments, we study the countermeasure strategies for ground-based phased array radars. Experimental results show that the improved Q-Learning algorithm can obtain the optimal allocation of jamming strategies with fewer iterations, improving countermeasure performance and preliminarily demonstrating the feasibility of this approach.

This paper introduces a novel adaptation approach for first-order pre- and de-emphasis filters, an essential tool in many speech and audio codecs to increase coding efficiency and perceived quality. The proposed zero-bit self-adaptation approach differs from classical forward and backward adaptation approaches in that the de-emphasis coefficient is estimated at the receiver, from the decoded pre-emphasized signal. This eliminates the need to transmit information that arises from forward adaptation as well as the signal-filter lag that is in-herent in backward adaptation. Evaluation results show that the de-emphasis coefficient can be estimated accurately from the decoded pre-emphasized signal and that the proposed zero-bit self-adaptation approach provides comparable subjective improvement to forward adaptation.

This paper proposes an unmanned aerial vehicle (UAV)-enabled wake-up radio (WuR) and data collection strategy for an Internet of Things (IoT) network. The considered model involves employing UAVs to awaken IoT devices from an ultralow power sleep mode through the transmission of WuR signals. Diverging from traditional methods where all IoT devices engage in data collection post-wake-up, the proposed framework centers on a more streamlined strategy. In the system model, a single UAV continuously traverses a specific region without hovering for the sake of waking-up nearby IoT devices. Specifically, solely IoT devices identifying valuable or unusual information transmit data back to the UAV upon a successful wake-up, which we refer to as opportunistic sensing. Hence, for reliable communication, it becomes important to determine the optimal height and velocity of the UAV while traversing the IoT region so as to maximize the probability that the UAV successfully wakes-up enough IoT devices to cover the field, followed by successful data collection of valuable sensed information. To this end, the paper proposes a low-complexity, fast in convergence, simple to implement efficient method to solve the non-convex optimization problem. The proposed algorithm relies on multidimensional bisection method, and is specifically tailored to determine the UAV's velocity and height, along with optimizing the device density. The numerical results in the paper validate the superior performance of the proposed algorithm when compared to conventional baselines.

In order to address the issues of high computational complexity, low accuracy, and the cumbersome manual feature extraction steps involved in traditional algorithms for modulating and recognizing underwater acoustic signals, this paper proposes a modulation recognition method based on Ghost-former for hydroacoustic signals. This approach harnesses the advantages of Ghost Net in generating more feature maps through cost-effective operations, along with a two-way bridge for global interaction. Experimental results with simulated signals demonstrate that this method achieves excellent recognition performance even with relatively low FLOPS.

The Internet connectivity in electronic devices has been progressively increasing over the years. While radio frequency (RF)-based communications dominate Internet of Things (IoT) applications, they face some issues such as interference and spectrum limitations. Visible light communications (VLC) uses light emitting diodes (LEDs) lights with intensity modulation to convey the signal and it has been demonstrated as a viable alter-native for indoor IoT scenarios. On the other hand, data clock synchronization between the transmitter (Tx) and the receiver (Rx) is crucial for reliable data transmission, mitigating timing errors and packet losses. Typical implementations are complex and require high-speed processing. This paper introduces an algorithm for data clock synchronization in a hybrid multiband carrierless amplitude and phase (m-CAP)/quadrature amplitude modulation(QAM) VLC system for IoT devices, ensuring accurate clock recovery that can be implemented in a low-cost microcontroller. The system achieves synchronization with a clock mismatch tolerance of up to 4200 ppm, supporting frames with a payload length up to 624 octets. By using averaging window sampling instead of a single sample acquisition, it is possible an extension of the payload length by approximately 208 octets.

This study proposes a penetration testing path planning method based on an improved potential field ant colony algorithm. First, the network topology is modeled as a graph structure, with each communication link assigned an attack cost weight. To overcome the issue of traditional artificial potential fields easily falling into local optima, this paper introduces a repulsion function that dynamically adjusts the repulsion intensity, weakening it as nodes approach the target system, thereby enhancing global search capability. The ant colony optimization algorithm is then employed, which iteratively optimizes path selection by simulating the pheromone release mechanism of ants. By combining the local search capability of the artificial potential field with the global search capability of the ant colony algorithm, the proposed improved algorithm demonstrates superior performance in terms of computation time, convergence speed, and path planning success rate. Experimental results in different network environments show that the improved algorithm’s performance increasingly surpasses that of other algorithms as network size grows, offering higher path planning success rates and faster convergence speeds. This study provides an efficient and reliable method for path planning in network security penetration testing.

Coupled canonical polyadic decomposition (C-CPD) can be used to represent a multistatic MIMO radar having a single transmit array and multiple receive arrays. Most of the existing algorithms of C-CPD model focus on the situation where the targets are stationary and they are limited to batch algorithms. However, in practice, each target may be moving, which makes the model dynamic. Therefore, the corresponding tracking algorithms are in urgent need. In this paper, we propose a C-CPD tracking method based on simultaneous diagonalization (SD) algorithm for multistatic MIMO radar. Theoretical and experimental results are provided to illustrate the advantages of the proposed algorithm compared with the batch C-CPD algorithms and CPD tracking methods.

Confidence and communication are both negatively impacted by stuttering, a speech condition that affects more than 70 million people globally. To improve fluency and intelligibility, the Stuttered Speech Recognition (SSR) system uses cutting-edge technologies such as the Weighted Mel Frequency Cepstral Coefficient algorithm and Machine Learning (ML) models to detect and fix speech defects. It can transform text into speech for assured communication and includes noise reduction for clarity. This goes beyond the scope of conventional speech recognition and holds great promise for helping stuttering people lead more fulfilling lives and be more integrated into society at large. The characteristic features of stuttering speech are an abundance of initial repetitions and prolongations. As a result, the stuttering episodes can be categorized using sound analysis. Finding specific stuttering occurrences, such as prolongations and repeats, in stuttered speech using a feature extraction technique is described in this study. To determine how effectively it can identify stuttering prolongations and repetitions, we apply the famous Mel Frequency Cepstral Coefficient (MFCC) feature extraction. Stuttering is a disease of neurodevelopment characterized by a lack of fluency in conventional speech patterns. Prolonged or repeated sounds, syllables, sentences, or phrases are examples of disfluency. Stuttering detection is challenging and complex since it involves pathology, psychology, acoustics, and signal processing, all of which make it an intriguing interdisciplinary domain study challenge. A thorough analysis of stuttering and disfluency classification methods is presented based on acoustic data as well as statistical and machine learning and deep learning approaches. This research is helpful for scholars, academicians and medical experts to identify the limitations in traditional models and to design efficient solutions for stuttered speech classification.

Effective traffic management and safety in Intelligent Transportation Systems (ITS) significantly benefit from various data points, with vehicle length being one important aspect. Current radar-based methods often fall short of demonstrating the capability to assess vehicle lengths in diverse traffic conditions. To bridge this gap, we introduce a novel algorithm employing time-frequency analysis of radar signals at a fixed range bin, enabling the estimation of the time vehicles of varying lengths and speeds take to cross this range bin. Assuming known vehicle velocities, this method allows the estimation of vehicle length. We develop a signal model of the vehicle's bulk motion extracted from its micro-Doppler signature. We then introduce three duration estimation methods: Maximum Likelihood Estimation (MLE) assuming Gaussian noise and two heuristic approaches utilising threshold calculations. Through testing on synthetic data and further validation using both simulated and real radar data, we evaluate the accuracy and computational efficiency of these methods. The results underscore the potential of our time-frequency analysis approach for vehicle length estimation, highlighting the prospect of non-invasive radar-based data collection systems in ITS.

We propose an algorithm to detect wormhole attacks based on the Address Resolution Protocol (ARP) for mobile networks which use On-demand Distance Vector (AODV) routing protocol. This novel approach differs from all existing methods, requiring no extra hardware or software equipment, and offers a simple detection method by avoiding complex calculations. Wormhole attacks, being among the most harmful, can result in data theft, discarding, tampering, and can even facilitate other attacks. Current defense algorithms typically require additional hardware or software and involve complex calculations at each node, sometimes failing in certain scenarios. Our algorithm aims to overcome these limitations.
