Special Issue Information

Dear Colleagues,

In the past decade, human beings have stepped into the era of information explosion, and the popularization of traffic-intensive applications across all types of communication terminals has led to an unprecedented increase in the demand for information and communication. Both wired and wireless communications play a fundamental role in the information age. With the rapid increase in the wireless communication demand, the development of wireless communication systems has encountered bottlenecks. The continuous advancement of 5G commercialization and the development and application of the Internet of Things, Internet of Vehicles, wireless body area networks, and wireless sensor networks have put forward new requirements for wireless networks. Beyond the requirements of greater bandwidth, reduced latency, and a certain level of intelligence, future wireless communication technologies necessitate remarkable advancements and substantial breakthroughs in diverse domains. These encompass microwave/millimeter-wave components and circuits, antenna technology, electromagnetic metasurfaces, resource allocation algorithms, network access strategies, and the integration of communication and sensing, among others.

Symmetry is an extraordinary characteristic that has been widely deployed in the research fields of wireless communication. This Special Issue invites original research that investigates the symmetry/asymmetry characteristics in wireless communication. We hope to spread knowledge among researchers, designers, manufacturers, and users in this exciting field with this Issue.

We look forward to receiving your contributions.

Hybrid ISAC-LSTM Architecture for Enhanced Target Tracking in Integrated Sensing and Communication Systems: A Symmetric Dual-Function Framework

Target tracking in integrated sensing and communication (ISAC) systems faces critical challenges due to complex interference patterns and dynamic resource allocation between radar sensing and wireless communication functions. Classical tracking algorithms struggle with the non-Gaussian noise characteristics inherent in ISAC environments. This paper addresses these limitations through a novel hybrid ISAC-LSTM architecture that enhances Extended Kalman Filter performance using intelligent machine learning corrections. The approach processes comprehensive feature vectors including baseline EKF states, ISAC-specific interference indicators, and innovation-based statistical occlusion detection. ISAC systems exhibit fundamental symmetry through dual sensing–communication operations sharing identical spectral and hardware resources, requiring balanced resource allocation, where αsensing+αcomm=1. The proposed hybrid architecture preserves this functional symmetry while achieving balanced performance across symmetric dual evaluation scenarios (normal and extreme conditions). Comprehensive evaluation across three realistic deployment scenarios demonstrates substantial performance improvements, achieving 21–24% RMSE reductions over classical methods (3.5–3.6 m vs. 4.6 m) with statistical significance confirmed through paired t-tests and cross-validation. The hybrid system incorporates fail-safe mechanisms ensuring reliable operation when machine learning components encounter errors, addressing critical deployment concerns for practical ISAC applications.
