K用户干扰信道:某些高斯信道的一般外界与总容量

K-user Interference Channels: General Outer Bound and Sum-capacity for Certain Gaussian Channels

Daniela Tuninetti

摘要:

本文导出了一般无记忆干扰信道容量域的一个外界。推导如下从一个概括的技术开发的克莱默和Etkin等人的高斯双用户信道。导出的边界是对任何无记忆通道有效的第一个已知的外部边界。在高斯噪声中,信道的类别,建议的界给出了总速率容量的确定,包括退化的信道和一类Z-信道。

英文摘要:

This paper derives an outer bound on the capacity region of a general memoryless interference channel with an arbitrary number of users. The derivation follows from a generalization of the techniques developed by Kramer and by Etkin et al for the Gaussian two-user channel. The derived bound is the first known outer bound valid for any memoryless channel. In Gaussian noise, classes of channels for which the proposed bound gives the sum-rate capacity are identified, including degraded channels and a class of Z-channels.
