摘要

非正交多址接入作为6G通信的关键技术，通过共享时频和空间资源，有效提高了资源利用率。然而，在基于功率域的NOMA系统中，连续干扰消除技术的应用可能引发用户隐私信息被窃听的安全问题。为解决这一问题，学界已提出多种方案，但这些方案通常依赖足够准确的信道状态信息，若信道估计精度不足，则其性能往往难以达到预期。为此，提出一种在信道估计存在误差的条件下基于估计误差补偿的物理层安全方案。首先通过低复杂度的额外估计实现对信道估计误差的补偿，然后基于补偿后获得的更准确的信道状态信息重新设计收发机。仿真结果表明，所提方案在不同信道估计误差和信噪比条件下均能显著提高系统的安全传输速率和传输可靠性。该方案为信道估计存在误差场景下的物理层安全问题提供了一种可行的解决办法。

Abstract

Non-orthogonal multiple access (NOMA) has been regarded as a key enabling technology for sixth-generation (6G) communications

since resource utilization was significantly enhanced by allowing multiple users to share the same time-frequency and spatial resources. However

in power-domain NOMA systems

user privacy information may be eavesdropped due to the application of successive interference cancellation

which introduces potential security vulnerabilities. To address this issue

various physical layer security schemes have been proposed in the literature

while their performance was highly dependent on sufficiently accurate channel state information (CSI). When channel estimation accuracy was insufficient

the achievable security performance often failed to meet expectations. To overcome this limitation

a physical layer security scheme based on channel estimation error compensation was proposed under imperfect CSI conditions. First

channel estimation errors were compensated through an additional low-complexity estimation process. Then

the transceiver was redesigned based on the more accurate CSI obtained after error compensation. Simulation results demonstrated that the proposed scheme significantly improved the secrecy rate and transmission reliability under different levels of channel estimation errors and signal-to-noise ratio. This scheme now provides a feasible solution to the physical layer security problem in scenarios where channel estimation errors exist.
