Special Issue Information

Dear Colleagues,

In today's digital era, the challenges of high-speed communication and big data processing have become paramount in the field of wireless communication. Symmetry, as a fundamental mathematical concept, is crucial in addressing the complexities encountered in high-speed and big data communication. This Special Issue aims to delve into the theory of symmetry and its practical applications in high-speed big data communication. We will explore not only the fundamental principles, but also the novel methodologies and technological innovations of symmetry theory in high-speed communication systems.

Moreover, this Special Issue will particularly highlight research on Multiple Input Multiple Output (MIMO) communication and array antenna technologies, focusing on their utilization of symmetry. MIMO technology has been widely employed to enhance data transmission rates and spectrum efficiency in communication systems, while array antennas play a crucial role in improving signal quality and enhancing communication coverage. The application of symmetry theory in MIMO system design, channel modeling, precoding, decoding techniques, as well as in array antenna design, beamforming, and spatial multiplexing, will be a pivotal area of study in this Special Issue.

These topics are popular in high-speed big data communication, MIMO communication, and array antennas. The aim of this Special Issue, entitled "Symmetry and Its Application in Wireless Communication", is to provide an overview of the latest advances in these wireless communication-related topics. We kindly invite all researchers working in the area to contribute to this Special Issue.

The experimental environment of the JUNO is a spherical container filled with a liquid scintillator (alkylbenzene) with a diameter of about 35 m. To observe neutrino interactions in alkylbenzene with photomultiplier tubes (PMTs) and to precisely measure the neutrino properties in this environment, it is necessary to design a high-precision localization system for the PMT device. In this paper, we report the design of an ultrasonic localization system with a symmetrical receiving array, based on the construction of an experimental setup that reproduces the configuration of JUNO’s environment. We show through positioning consistency and accuracy measurements that the ultrasonic localization system has a high localization accuracy and can perform effective localization in an alkylbenzene solution with 98% purity.

Underwater wireless acoustic positioning technology uses the geometric relationship between a target and a receiving array to determine the target’s position by measuring distances between the target and the array elements, that the receiving array is usually symmetry in space. It is an indirect measurement approach, so ranging errors can significantly impact positioning accuracy due to error transmission effects. To improve precision, a similarity-matched localization algorithm based on the L-p norm (LPM) is introduced. This algorithm constructs a distance vector model with environmental parameters and performs similarity analysis by computing the L-p norm of the distance vector and a reference copy vector for three-dimensional localization in the observation area. Unlike conventional methods, this technology directly matches distance vectors without coupling error transmission, thereby enhancing positioning accuracy even though it remains contingent upon ranging precision. To validate the algorithm’s efficacy, Monte Carlo simulations are employed to analyze the distribution patterns of positioning errors in both horizontal and three-dimensional spaces. The results show an improvement from a mean positioning error of 0.0475 m to 0.0250 m and a decrease in error standard deviation from 0.0240 m to 0.0092 m. The results indicate that LPM offers improved accuracy and robustness by circumventing traditional error transmission issues. Full article

This paper examines the communication difficulties encountered in cross-media wireless optical transmission through simulated research on the utilization of orthogonal time and frequency space (OTFS) modulation technology. Our analysis and comparison demonstrate that OTFS significantly improves the reliability and throughput of data transmission in intricate multipath channel settings. In contrast to conventional orthogonal frequency division multiplexing (OFDM) technology, OTFS displays better resilience and transmission effectiveness. We foresee additional enhancements and progress in OTFS technology to present a sturdier and more efficient resolution for wireless communication, thereby providing valuable perspectives and encouragement for associated research initiatives. Our results underscore the capability of OTFS technology to transform wireless communication systems in demanding multipath channel conditions. Full article
