混合强-极强干扰下$K$ -用户离散无记忆干扰信道的容量域

Capacity Region of $K$-User Discrete Memoryless Interference Channels with a Mixed Strong-Very Strong Interference

G. Abhinav, B. Sundar Rajan

摘要:

在\cite{ChS}中建立了强-极强混合干扰下3用户高斯干扰信道的容量域。在\cite{ChS}中考虑的混合强-非常强干扰条件对应于在每个接收机处干扰信号之一强而另一个非常强的情况。在本文中,我们推导出$K$ -用户$(K\geq 3)$离散无记忆干扰信道(DMIC)的容量区域与混合强-非常强的干扰。这对应于在每个接收机处干扰信号之一强而其它$(K-2)$干扰信号非常强的情况。作为特殊情况,这包括具有混合强-非常强干扰的3用户DMIC。证明是专门的3用户GIC的情况下,因此,一个替代的简单推导的容量区域的3用户GIC与混合强-非常强的干扰。

英文摘要:

The capacity region of the 3-user Gaussian Interference Channel (GIC) with mixed strong-very strong interference was established in \cite{ChS}. The mixed strong-very strong interference conditions considered in \cite{ChS} correspond to the case where, at each receiver, one of the interfering signals is strong and the other is very strong. In this paper, we derive the capacity region of $K$-user $(K\geq 3)$ Discrete Memoryless Interference Channels (DMICs) with a mixed strong-very strong interference. This corresponds to the case where, at each receiver one of the interfering signals is strong and the other $(K-2)$ interfering signals are very strong. This includes, as a special case, the 3-user DMIC with mixed strong-very strong interference. The proof is specialized to the 3-user GIC case and hence an alternative simpler derivation for the capacity region of the 3-user GIC with mixed strong-very strong interference is provided.
