Spectrum sensing based on a single user suffers from low detection performance due to fading, shadowing, and hidden node problems. Cooperative spectrum sensing (CSS) is thought to be a potential method to overcome these issues and improve detection performance in determining the available spectrum in cognitive radio (CR). However, CSS suffers in case of erroneous reporting channels, and it is also susceptible to Byzantine attacks by malicious users (MUs). In this paper, we first analyze the traditional CSS under erroneous feedback channels. And then, we extend the analysis to include erroneous reporting channels in the presence of the Byzantine attack. We propose a single decision reporting (SD-R) algorithm immune to erroneous reporting channels. The proposed algorithm also improves the performance under the Byzantine attack. With the proposed algorithm, MUs can attempt only false alarm attacks, whereas the miss detection attack is not possible. An extensive analysis is carried out, and the plots are shown to prove the superiority of the proposed algorithm.

由于衰落、阴影和隐藏节点问题，基于单个用户的频谱感知检测性能低下。协作频谱感知 (CSS) 被认为是克服这些问题并提高在确定认知无线电 (CR) 中可用频谱方面的检测性能的潜在方法。然而，CSS 在错误报告渠道的情况下会受到影响，并且它也容易受到恶意用户 (MU) 的拜占庭式攻击。在本文中，我们首先分析了错误反馈渠道下的传统 CSS。然后，我们将分析扩展到包括存在拜占庭攻击时的错误报告渠道。我们提出了一种不受错误报告渠道影响的单一决策报告 (SD-R) 算法。所提出的算法还提高了拜占庭攻击下的性能。使用所提出的算法，MU 只能尝试误报攻击，而无法进行漏检攻击。进行了广泛的分析，并显示了图表以证明所提出算法的优越性。
