摘要

针对太赫兹（THz）链路传输距离短的问题，研究了智能反射表面（RIS）辅助的混合双跳射频（RF）/THz系统的性能。RIS用于增强信号强度，从而提升系统性能。采用固定增益放大转发协议，推导了混合RF/THz 链路端到端信噪比的累积分布函数和概率密度函数表达式。利用这些统计特性，进一步推导了该混合中继系统的中断概率、平均误码率和平均信道容量的分析表达式。此外，还对中断概率和平均误码率进行了渐近分析，获得了混合RF/THz系统的分集度。仿真结果表明，RIS可以有效提高混合RF/THz系统的性能。此外，系统的性能还与信道衰落参数、指向误差和距离有关。

Abstract

To solve the problem of the short transmission distance of terahertz (THz) links

the performance of the reconfigurable intelligent surface (RIS)-assisted mixed dual-hop radio frequency (RF)/THz system was studied.An RIS was used to enhance signal strength

thereby improving the system performance.Using the fixed-gain amplify-and-forward protocol

the cumulative distribution function and probability density function of the end-to-end signal-to-noise ratio of the RF/THz link were derived.Capitalizing on the statistical characteristics

the analytical expressions of outage probability

average bit error rate

and average channel capacity of the mixed relaying system were further derived.In addition

the asymptotic analyses of the outage probability and the average bit error rate were carried out to obtain the diversity order of the mixed RF/THz system.Simulation results show that the RIS can effectively improve the performance of the mixed RF/THz system.Furthermore

the system performance is related to the channel fading

pointing errors

and propagation distance.
