摘要
在本文中，我们分析了瑞利块衰落信道下超奈奎斯特（FTN）信令中隐蔽通信的性能。同时考虑了基于贝叶斯准则和基于Kullback-Leibler（KL）散度的隐蔽性约束。特别地，对于基于KL散度的约束，我们证明了FTN信令下的最大发射功率和隐蔽速率均高于奈奎斯特信令下的相应值。数值结果与分析一致，并验证了FTN信令在实现隐蔽数据传输方面的优势。

备注
We have corrected the typos and inappropriate description throughout the paper as reviewers suggested. We have proved the superiority of FTN signaling on covert communications with the same detection time duration at Willie in Theorem 3 and renewed the simulation results in Section V as Reviewer 2 suggested.
