线性确定性干扰信道的带噪输出反馈容量

Noisy Channel-Output Feedback Capacity of the Linear Deterministic Interference Channel

Victor Quintero, Samir M. Perlaza, Jean-Marie Gorce

摘要:

本文研究了带噪声输出反馈的两用户线性确定性干扰信道的容量域。该结果允许识别几种非对称场景,其中在发射机-接收机对中的仅一个中实施信道输出反馈与在两个链路中实施它一样有益,就可实现的单独速率和速率改进而言。没有反馈的案例。在其他场景中,在任何发射机-接收机对中使用信道输出反馈在可实现的单独速率改进方面仅有益于两对中的一对,或者简单地,它被证明是无用的,即,即使在反馈链路中完全没有噪声的情况下,具有和不具有反馈的容量区域也是相同的。

英文摘要:

In this paper, the capacity region of the two-user linear deterministic (LD) interference channel with noisy output feedback (IC-NOF) is fully characterized. This result allows the identification of several asymmetric scenarios in which imple- menting channel-output feedback in only one of the transmitter- receiver pairs is as beneficial as implementing it in both links, in terms of achievable individual rate and sum-rate improvements w.r.t. the case without feedback. In other scenarios, the use of channel-output feedback in any of the transmitter-receiver pairs benefits only one of the two pairs in terms of achievable individual rate improvements or simply, it turns out to be useless, i.e., the capacity regions with and without feedback turn out to be identical even in the full absence of noise in the feedback links.
