Efficient Multi-Task Learning in Multi-User Multiple Input Multiple Output Systems Integrated Orthogonal Frequency Division Multiplexing Systems: A Hybrid Amalgamated Convolutional Neural Network-Bidirectional Long Short-Term Memory Approach

Therefore, in today’s wireless communication systems and in particular, the Multi-User-Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing (MU-MIMO-OFDM) systems, channel estimation, the detection, and mitigation of the attack are important to ensure the safe operation of a system. Current approaches use distinct procedures for completing these jobs, and this causes high computational expenses, longer response times, and decreased performance of the system. In this work, a multi-task learning (MTL) framework is introduced to develop a new end-to-end deep learning solution of an Amalgamated Convolutional Neural Network (ACNN) for spatial feature extraction and a Bidirectional Long Short-Term Memory (Bi-LSTM) for temporal attack detection. The proposed system is effective in handling these tasks together because that would mean maximum efficiency and accuracy. To enhance the model’s efficiency, a Green Anaconda Optimization (GAO) algorithm is used to solve the multi-task loss function and enhance convergence rate and solution quality. The presented GAO approach provides a good balance between channel estimation, attack detection, and mitigation since GAO adapts the model parameters in the training process. Most of the current methods give slow convergence rates, and high computational costs, and are not very suitable for scale-up, especially in dynamic systems. These limitations make them unadoptable for real-time operations and analysis. The challenges described above are addressed by the proposed hybrid model with GAO, which is therefore ideal for modern secure wireless communication systems due to the reduced computational overhead and faster response time. The model reaches a first-level accuracy of 99% and costs 70 GFLOPs and 35 ms latency.

Polydimethylsiloxane Based Flexible Antenna with Enhanced Performance and High-Efficiency for Biomedical Applications
Deepthy Grace Sudarsanan, Nesasudha Moses, and Karthikeyan Thavittupalayam Angappan
King Mongkut's University of Technology North Bangkok
PDMS is frequently utilized in the biomedical field because of its biocompatibility. The PDMS finds applications in medical implants, cardiovascular flow replication, and in the biomedical industry. This paper presents an innovative antenna design optimized for biomedical applications operating in the Industrial, Scientific, and Medical (ISM) band (2.4–2.5 GHz). The proposed antenna features a compact, flexible structure utilizing a Polydimethylsiloxane (PDMS) substrate to prioritize patient safety and comfort. For PDMS, the loss tangent is 0.0134 and the dielectric constant is 2.71. The design process employs parametric optimization to achieve a low-profile configuration with a wide impedance bandwidth and better radiation characteristics. Simulations and experimental validation using a multi-layered tissue phantom demonstrate superior performance, achieving a return loss below -10 dB across the ISM band. Additionally, Specific Absorption Rate (SAR) measurements confirm compliance with international safety standards, ensuring minimal electromagnetic exposure. PDMS-based flexible antennas hold promise for biomedical applications, but many existing designs face challenges related to limited gain, narrow bandwidth, and poor mechanical stability under continuous body movement. This highlights the need for more reliable and adaptable antenna solutions for on-body use. This study underscores the potential of the proposed ISM-band antenna to enhance the functionality and efficiency of biomedical communication systems, driving advancements in telemedicine and personalized healthcare solutions.

Joint Power and Delay Optimization-Based Resource Allocation in Mu-MIMO-OFDM System: Deep Convolutional Red Piranha Pyramid-Dilated Neural Network

Wiley
ABSTRACTIn general, Multi‐User Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MU‐MIMO‐OFDM) enables multiple users to simultaneously communicate with a single base station using multiple antennas and OFDM modulation. Nevertheless, resource allocation challenges such as power management and delay optimization arise within MU‐MIMO‐OFDM systems, requiring sophisticated solutions to ensure efficient use of resources and optimal system performance. Thus, joint power and delay optimization‐based resource allocation using a Deep Convolutional Pyramid‐Dilated Neural Network (DCPDNN) with Red piranha optimization and Optimal Delay Scheduling conflict graphs Algorithm (DCPDNN‐RPO‐ODSCGA) in MU‐MIMO‐OFDM system is proposed in this presented research. The proposed mechanism is performed in two stages: power allocation and delay optimization. In the first stage, through a Deep Convolutional Pyramid‐Dilated Neural Network (DCPDNN), which aims to maximize throughput, the network resources are distributed to user equipment (UEs) based on power and transmission rate. To reduce the loss function, Red Piranha Optimization (RPO) is proposed to optimize the layers of DCPDNN. In the second stage, the Optimal Delay Scheduling conflict graphs Algorithm (ODSCGA) is proposed for the optimizing delay in the MU‐MIMO‐OFDM system. The multiracial envelope procedure and service curve for traffic flows in the uplink transmission are used in the ODSCGA approach to estimate the delay‐bound value. Ideas like the maximal weight independent set and optimal conflict graph are also utilized. The simulations of DCPDNN‐RPO‐ODSCGA were conducted using MATLAB software. Thus, the proposed approach has attained higher spectral capacity, higher fairness index, and increased cumulative distribution function (CDF), 29.74%, 32.98%, and 16.46% lower loss rate, 28.05%, 24.09%, and 17.45% improved energy efficiency, 15.09%, 13.78%, and 12.05% lower processing time than other conventional approaches like MPQM‐SCA, Hyb‐BF‐DSA, and SIA‐FDBD methods, respectively.

Abstract A Polydimethylsiloxane (PDMS) based antenna is designed for skin tumor detection. The antenna functions at 2.45 GHz with a bandwidth of 2.30–2.64 GHz working in the ISM (Industrial, Scientific, and Medical) band. The size of the antenna is 40 × 40 × 1 mm3. This antenna detects tumors in the skin by considering the variations in values of the E-field, J-surf, and H-field. Various analyses such as the distance between the patch and stacked layer skin phantom for different tumor sizes and input power to the antenna are changed and antenna performance is observed. A significant amount of changes is attained which denotes the presence of the tumor. The proposed antenna is fabricated and the corresponding results are analyzed in the Anechoic Chamber. The antenna has an efficiency of 99 % with a Specific Absorption Rate of 1.3846 W/kg which is lower than 1.6 W/kg as per the recommendations of FCC standard.

Abstract This research work presents an implantable antenna that operates at 5.8 GHz. By using a radiator with a loop-based design, the antenna can be made smaller. Radiator is made up of three connected rectangular loops. On the substrate’s back side, an I-shaped ground plane is used. As substrate and superstrate, polydimethylsiloxane (PDMS) with dimensions of 7 mm × 5 mm × 0.3 mm is used. The conducting sections are made using copper foil that is 30 µm thick. The suggested antenna is examined by the implantable medical device using realistic human scalp phantom models and a homogenous skin box. Simulated study revealed that it operates around 5.8 GHz with a bandwidth from 5.69 to 5.92 GHz. The specific absorption rate was 0.28 and 0.26 W/kg for skin box and human scalp phantoms, respectively, at 1 mW input power across 1 g volume tissue.
