Quantum-inspired sidelobe canceller beamformer with bidirectional beam scanning and sectorized jamming mitigation properties Avishek Chakraborty, Indrasen Singh, Chakradhar Adupa International Journal of Microwave and Wireless Technologies, 2026 The proposed research aims to develop an efficient sidelobe canceller beamforming antenna array for scanning and anti-jamming purposes in radars with time-modulation. Time-modulated antennas are unconventional alternatives to phased arrays, in which the phase deviations between the impinging signals can be controlled by suitably switching ON and OFF the array elements at different time instants. This research addresses the design of a quantum-inspired optimal time-modulated beamformer, aiming for a broad scan coverage of 90° towards broadside. The scanned beams are generated using quantum algorithm-inspired time schemes, in which the ON times of each element are optimized to achieve the optimal radiation characteristics. The beamformer simultaneously aimed to suppress the sidelobes of the scanned radiation patterns. The proposed beamformer is designed for an 8-element antenna array, and the incorporation of time-modulation and its inherent harmonics generation enables simultaneous beam scanning over a desired region. The scanned patterns with reduced sidelobes are further exploited for the strategic null placement by proposing the time-modulated single-point anti-jammers. The concept is further extended, and an 8-element beamformer is developed for sectorized anti-jamming to show the efficiency, effectiveness, and robustness of the proposed research. Multiple sectors in the angular region are targeted by exploiting the harmonics and suppressing them below a desired level. The sidelobe canceller beamformer also demonstrates decent performance, suppressing sidelobes below 20 dB across all applications. The radiation power efficiency of the beamformer is more than 78%. The proposed sidelobe canceller time-modulated beamformer is also compared with other related research for a detailed comparison.
Secrecy outage probability and strictly positive secrecy capacity of UAV assisted cooperative NOMA system with two untrusted destinations Mohd Javed Khan, Saif Ahmad, Indrasen Singh, Umesh Kumar Sahu Scientific Reports, 2025 The volume of confidential information transmitted over 5G networks has increased rapidly due to the widespread adoption of large machine-type communication and Internet of Things (IoT) devices. Secrecy outage probability (SOP) and strictly positive secrecy capacity (SPSC) parameters are crucial parameters used in evaluating the security of wireless systems, particularly in situations where maintaining secrecy is essential. Also, Non-orthogonal multiple access (NOMA) has the potential to improve the performance of wireless communication systems due to its higher spectral efficiency, improved fairness in resource allocation, and enhanced coverage and connectivity. In this paper, we investigate the secrecy performance of unmanned aerial vehicles (UAV) assisted cooperative NOMA system with a half duplex protocol based amplify and forward relay over the Rayleigh fading channel in presence of two eavesdroppers for downlink communication. We derive SOP and SPSC of the proposed system model and analyze its performance in terms of the illegal SNR of eavesdroppers, power allocation coefficient, information rates and Rayleigh channel parameters. Simulation results demonstrate that SOP decreases with a higher value of power allocation coefficient and lower values of the illegal SNR of eavesdropper and lower information rates. SPSC increases with high values of power allocation coefficient of far destination and decreases with lower values of illegal SNR of eavesdroppers and Rayleigh channel parameters. Analytical simulations are verified using Monte Carlo simulations.
Hybrid cryptographic approach for strengthening IoT and 5G/B5G network security Aman Kumar, Prashutosh Singh, Dhananjay Pandurang Kamble, Indrasen Singh Scientific Reports, 2025 The rapid evolution of fifth-generation (5G) and beyond (B5G) networks has introduced significant security challenges, necessitating advanced cryptographic mechanisms to protect sensitive data during transmission. Traditional encryption models often struggle to balance security, computational efficiency, and adaptability to dynamic network conditions. This study proposes a novel hybrid cryptographic framework integrating the Advanced Encryption Standard (AES), Data Encryption Standard (DES), and Rivest–Shamir–Adleman (RSA) algorithms. AES and DES provide high-speed symmetric encryption for efficient data protection, while RSA enables secure key exchange and authentication. The integration of dynamic round keys enhances encryption complexity, improving resistance to cryptanalytic attacks. Performance evaluations, including encryption and decryption time analysis, data expansion metrics, and throughput assessments, demonstrate that the proposed framework achieves an optimal balance between security and computational overhead. Benchmark comparisons with traditional and post-quantum cryptographic models highlight the superior efficiency and reduced data expansion of the hybrid approach. Furthermore, practical implementation on ESP32 hardware confirms the model’s feasibility for real-time encryption in resource-constrained environments typical of 5G applications. This scalable and flexible encryption paradigm addresses current and emerging security requirements in high-speed wireless networks, with future work focusing on integration with quantum-resistant cryptographic mechanisms to enhance resilience against evolving cyber threats. Experimental results show that the hybrid model achieves up to 30% higher throughput, 10–15% lower data expansion, and reduced encryption/decryption time compared to baseline algorithms, with successful ESP32 implementation and 100% decryption accuracy for key sizes up to 128 bits.
HDL-ACO hybrid deep learning and ant colony optimization for ocular optical coherence tomography image classification Shivani Agarwal, Anand Kumar Dohare, Pranshu Saxena, Jagendra Singh, Indrasen Singh, et al. Scientific Reports, 2025 Optical Coherence Tomography (OCT) plays a crucial role in diagnosing ocular diseases, yet conventional CNN-based models face limitations such as high computational overhead, noise sensitivity, and data imbalance. This paper introduces HDL-ACO, a novel Hybrid Deep Learning (HDL) framework that integrates Convolutional Neural Networks with Ant Colony Optimization (ACO) to enhance classification accuracy and computational efficiency. The proposed methodology involves pre-processing the OCT dataset using discrete wavelet transform and ACO-optimized augmentation, followed by multiscale patch embedding to generate image patches of varying sizes. The hybrid deep learning model leverages ACO-based hyperparameter optimization to enhance feature selection and training efficiency. Furthermore, a Transformer-based feature extraction module integrates content-aware embeddings, multi-head self-attention, and feedforward neural networks to improve classification performance. Experimental results demonstrate that HDL-ACO outperforms state-of-the-art models, including ResNet-50, VGG-16, and XGBoost, achieving 95% training accuracy and 93% validation accuracy. The proposed framework offers a scalable, resource-efficient solution for real-time clinical OCT image classification.
Defected Ground Structure (DGS) Based MIMO Antenna Array With Decent Isolation Characteristics for Satellite Communications in Unified S-Band (USB) Avishek Chakraborty, Ravi Shankar Saxena, Indrasen Singh, Jatinder Kaur, Ramneet Kaur, et al. Radio Science, 2025 This research focuses on developing an efficient, high‐isolation Multi‐Input Multi‐Output (MIMO) antenna array for Mobile Satellite Services (MSS). A portion of the S‐band (2–4 GHz) ranging from 2 to 2.2 GHz, known as Unified S‐Band (USB), is utilized for MSS, particularly for Space‐to‐Earth communications. The ultimate objective of the proposed MIMO is to cover the USB spectrum and resonate at 2.2 GHz. As the first step of the design process, a meandered line (ML) monopole patch with good radiation characteristics in the desired frequency band is designed. Then, the mirror image of the proposed ML radiator is added to the design to form a two‐element ML‐MIMO array. A well‐designed MIMO is highly beneficial for boosting the reliabilities, channel capacities, and frequency reuse in next‐generation communication. But at the same time, it inherently increases the coupling effect between closely placed radiators, which may degrade the performance of the overall design. To overcome the coupling effect, a defected ground structure (DGS) is proposed in the partial ground plane of the ML‐MIMO. The proposed DGS intends to reduce the coupling effects by perturbing the surface current distributions in the partial ground plane. Meanwhile, the DGS also enhances the compactness of the entire structure by boosting the gain and reducing the total weight. MIMO parameter metrics such as axial ratio below 3 dB, envelope correlation coefficient less than 0.0005, and a diversity gain close to 10 are also aimed by simultaneously reducing the mutual coupling below −30 dB and return loss below −25 dB for standard MIMO applications. The ML‐MIMO is then fabricated on a FR4 substrate with a dimension of 40 mm by 48 mm, and measured. The simulated outcomes are found to be in close approximation with the measurement outcomes. A detailed comparison and trade‐off analysis of the proposed design with respect to other contemporary research is also presented for further validation.
