In this paper, we propose two feedback coding schemes for the action-dependent wiretap channel with noncausal state at the transmitter. The first scheme follows from the already existing secret key based feedback coding scheme for the wiretap channel. The second one follows from our recently proposed hybrid feedback scheme for the wiretap channel. We show that, for the action-dependent wiretap channel with noncausal state at the transmitter, the second feedback scheme performs better than the first one, and the capacity results of this paper are further explained via a Gaussian example, which we call the action-dependent dirty paper wiretap channel with noiseless feedback.
在本文中，我们针对发射端具有非因果状态的动作相关窃听信道提出了两种反馈编码方案。第一种方案源自已有的针对窃听信道基于秘密密钥的反馈编码方案。第二种方案源自我们最近为窃听信道提出的混合反馈方案。我们表明，对于发射端具有非因果状态的动作相关窃听信道，第二种反馈方案比第一种表现更好，并且本文的容量结果通过一个高斯示例进一步解释，我们将其称为具有无噪声反馈的动作相关脏纸窃听信道。
