The inherent characteristics of space shift keying (SSK) had generated substantial research interest in the domain of multiple-input multiple-output (MIMO) systems, resulting in the development of hardware-based implementations. With the emergence of software-defined radio (SDR) technologies, radios could be implemented through software solutions. One prominent open-source SDR toolkit, GNU Radio, offered a comprehensive suite of signal processing blocks tailored for this purpose. In this study, a 2 × 2 SSK MIMO system was implemented using GNU Radio, inclusive of the deployment of advanced algorithms on a commercially available SDR platform for real-time transmission and reception. To assess the effectiveness of the implementation, meticulous comparisons were made between measurement results and simulation outcomes, revealing a high degree of accuracy in matching for a Rician fading channel characterized by a $K$ -factor of 2.5.

Shrimp farming has traditionally served as a crucial source of seafood and revenue for coastal countries, filling the rapid growth demand, especially in Bangladesh. However, the White Spot Syndrome Virus(WSSV) creates and constantly threatens the global shrimp population, impacting the economic and ecological systems. Recently, researchers have tried to predict disease, but no studies have achieved significant accuracy using ML and DL algorithms. In this study, we have proposed an optimized CNNRF-Ensemble model for predicting WSSV using multifaceted data, including geographical features, environmental attributes, farm characteristics, operational practices, and socioeconomic indicators. Our proposed model achieved 95.714% accuracy in sequential model and afterwards, combining with RandomForestClassifier in Ensemble learning we obtained 99.99% accuracy. Our study suggested deep learning as an accurate, easy and low-cost method to predict shrimp WSSV, which helps to predict viruses and create awareness of shrimp firming.

The performance of two-way full-duplex communications with the help of reconfigurable intelligent surface (RIS) under phase noise is investigated in this work. Particularly, we study the outage probability, the average rate of each end-user, and the average sum rate of the whole network under both optimal phase-shift and random phase-shift design. Simulation results via the Monte-Carlo method are given to confirm the advantages of the optimal design compared with the random one and to unveil the impact of some essential parameters such as the number of RIS elements, and the number of quantization bits on the system performance. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

In the era of modern industries, use of advanced machines has increased the productivity of plants. Defect of such complex machines can increase the downtime and hence reduce productivity and ultimately the profit. Proper maintenance of systems is very crucial to ensure trouble free operation of machines. Predictive Maintenance techniques are those techniques which are used for identification of fault in its early stage. This avoids the sudden unavailability of machines and reduces the downtime. Predictive Maintenance techniques using vibration analysis is one of the very popular methods of Condition Monitoring. These techniques are evolving rapidly due to their efficient detection of fault in its incipient stage. However, non-stationary of the vibration signal produced particularly in belts in belt drive systems using conventional techniques of signal processing poses challenges. In this project work, the application of advanced signal processing techniques is investigated for the automatic fault detection in belts. This project work is focused on developing a novel concept of vibration signal processing for the automatic fault detection in belts using wavelet analysis and the belt condition classification and prediction using Machine Learning algorithms. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

The significant advancements in research within the domain of advanced Driver-Assistance Systems (ADAS) have been significantly propelled by the integration of Artificial Intelligence (AI) and Deep Learning (DL). The detection and classification of traffic signals are pivotal for ensuring driver safety and comfort, prompting the development of numerous detection and classification methodologies in recent times. Convolutional Neural Networks (CNNs) and Field Programmable Gate Arrays (FPGAs) have individually demonstrated notable efficacy in signal processing, image detection, and image classification tasks. However, the amalgamation of CNNs and FPGAs for traffic signal classification offers enhanced flexibility, accuracy, and resource efficiency. This study proposes a software-hardware co-design approach for the development of a resource-efficient real-time traffic signal classification system tailored for FPGAs utilizing the CNN algorithm. The software implementation has been carried out within the TensorFlow framework, while the hardware implementation is executed via the Xilinx Vivado 2023.1 platform and rigorously evaluated using the Xilinx ZCU102 FPGA board. Experimental findings demonstrate that the traffic signal classification accuracy can attain approximately 99.98% at a frame rate of 84139 frames per second (FPS) on the FPGA platform, with a power consumption of 4.4W. The exceptionally low latency and heightened accuracy exhibited by the proposed system render it highly advantageous for ADAS and other safety-critical applications.

In conventional interactive multiple model (IMM) algorithm, the fixed transition probability matrix results in slow model switching and low tracking accuracy. Existing adaptive transition probability IMM algorithms still suffer from large errors during model switching. This paper proposes a model switching detection-aided adaptive transition probability matrix IMM algorithm. To deal with model switch time delay, a transition probability correction function is established, capable of dynamically and rapidly adjusting the transition probabilities. And a model switching detection method is proposed to improve tracking accuracy during model switching. By the numerical simulation, the method's efficacy is substantiated and confirmed.

Retrieval-augmented citation generation (RACG) helps users trust the large language model output by retrieving evidence from reliable sources. However, most current RACG research focuses on single-language tasks, particularly in English, and overlooks the need for cross-lingual evidence retrieval and utilization in real-world applications. To address this issue, we introduce a plug-and-play Retrieval-Augmented Multilingual Citation Generation method (RAMCG) which uses a multilingual retriever to identify relevant evidence from a multilingual knowledge base. The evidence is then combined with the query and processed by a multilingual citation generator. The result is citations that are both accurate and comprehensive. Experiments show that RAMCG outperforms baseline methods in multilingual citation generation and is well-suited for practical use.

This study presents a preliminary investigation into the feasibility of controlling a prosthetic arm using electroencephalography (EEG) signals. EEG data was collected and pre-processed to isolate relevant brain activity associated with hand movements. Basic feature extraction techniques were applied to quantify these patterns, followed by a simple classification algorithm to distinguish between hand open and closed states. While demonstrating the potential of EEG-based control, this research highlights the need for advanced signal processing, robust feature engineering, and sophisticated machine learning models to achieve accurate and reliable prosthetic control.

The transition of data and clock signals between high and low states in electronic devices creates electromagnetic radiation according to Maxwell's equations. These unintentional emissions, called emanation, may have a significant correlation with the original information-carrying signal and form an information leakage source, bypassing secure cryptographic methods at both hardware and software levels. Information extraction exploiting compromising emanations poses a major threat to information security. Shielding the devices and cables along with setting a control perimeter for a sensitive facility are the most commonly used preventive measures. These countermeasures raise the research need for the longest detection range of exploitable emanation and the efficacy of commercial shielding. In this work, using data collected from 3 types of commercial HDMI cables (unshielded, single-shielded, and double-shielded) in an office environment, we have shown that the CNN-based detection method outperforms the traditional threshold-based detection method and improves the detection range from 4 m to 22.5 m for an iso-accuracy of similar to 95%. Also, for an iso-distance of 16 m, the CNN-based method provides similar to 100% accuracy, compared to similar to 88.5% using the threshold-based method. The significant performance boost is achieved by treating the FFT plots as images and training a residual neural network (ResNet) with the data so that it learns to identify the impulse-like emanation peaks even in the presence of other interfering signals. A comparison has been made among the emanation power from the 3 types of HDMI cables to judge the efficacy of multi-layer shielding. Finally, a distinction has been made between monitor contents, i.e., still image vs video, with an accuracy of 91.7% at a distance of 16 m. This distinction bridges the gap between emanation-based image and video reconstruction algorithms.

Traditional analog-to-digital converters (ADCs) often struggle to balance high sampling rates with power efficiency, limiting their effectiveness in advanced radar and communication systems. Neuromorphic ADCs capture samples only when a signal crosses a specific threshold. This asynchronous sampling strategy effectively compresses incoming datastreams, enabling neuromorphic ADCs to achieve higher sampling rates at reduced power consumption compared to conventional ADCs. However, existing algorithms are poorly suited for processing the asynchronous samples. Conventional techniques like matched filters are inapplicable and most established deep learning algorithms expect regularly sampled data. This work introduces a spiking neural network (SNN) architecture specifically designed for processing asynchronous radar samples. Our novel approach is applied to Radar High-Resolution Range Profile (HRRP) based target classification. Remarkably, our experiments demonstrate that combining a neuromorphic ADC with an SNN achieves performance on par with high-sample-rate conventional ADCs paired with Convolutional Neural Networks (CNNs) while reducing the overall sampling rate by more than 95%.
