干扰多址信道时干扰作为噪声处理的最优性

On the Optimality of Treating Interference as Noise for Interfering Multiple Access Channels

Hamdi Joudeh, Bruno Clerckx

摘要:

在本文中,我们期待在高斯干扰多址接入信道(IMAC)的问题,作为噪声(TIN)的干扰。所考虑的网络包括$K$相互干扰的多址信道(MAC),每个MAC由两个发送器组成,发送独立的消息到一个接收器。我们定义的TIN方案为这个通道,其中每个MAC执行其容量实现策略的功率控制版本,同时将来自所有其他MAC的干扰视为噪声。我们描述了一个可实现的广义自由度(GDoF)的区域下的TIN计划,并确定一个政权的参数(在信道强度水平方面),该区域是最佳的。

英文摘要:

In this paper, we look at the problem of treating interference as noise (TIN) in the Gaussian interfering multiple access channel (IMAC). The considered network comprises $K$ mutually interfering multiple access channels (MACs), each consisting of two transmitters communicating independent messages to one receiver. We define the TIN scheme for this channel as one in which each MAC performs a power controlled version of its capacity-achieving strategy while treating interference from all other MACs as noise. We characterize an achievable generalized degrees-of-freedom (GDoF) region under the TIN scheme and identify a regime of parameters (in terms of channel strength levels) where this region is optimal.
