Abstract

In this work, the performance of a mixed radio frequency underwater radio-acoustic communication (RF-UAC) relaying system assisted by an active reconfigurable intelligent surface (A-RIS) is investigated. A buoy is used as a relay for communication between the ground base station and the underwater target. Both the fixed gain amplify-and-forward (AF) and decode-and-forward (DF) relaying protocols are considered. The

$\kappa -\mu$

shadowed distribution model is employed to delineate the characteristics of the UAC link. Utilizing this model, we extract the cumulative distribution function (CDF) and probability density function (PDF) of the end-to-end signal-to-noise ratio (SNR). To assess the system performance, we further derive the outage probability (OP), bit error rate (BER), and average channel capacity (AC). Additionally, we conduct an asymptotic analysis of the OP and derive tight upper and lower bounds for the AC. The accuracy of our theoretical analysis is validated through Monte Carlo simulations.

主动-RIS 辅助混合射频-UAC 系统的性能评估

在本工作中，研究了由主动可重构智能表面（a - ris）辅助的混合射频水下无线电-声通信（RF-UAC）中继系统的性能。浮标用作地面基站和水下目标之间通信的中继器。同时考虑了固定增益放大转发（AF）和解码转发（DF）中继协议。采用$\kappa -\mu$阴影分布模型来描述UAC链路的特性。利用该模型提取端到端信噪比的累积分布函数（CDF）和概率密度函数（PDF）。为了评估系统性能，我们进一步推导出中断概率（OP）、误码率（BER）和平均信道容量（AC）。此外，我们对OP进行了渐近分析，并推导出AC的严密上界和下界。通过蒙特卡罗模拟验证了我们理论分析的准确性。

期刊介绍： The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
