关于干扰信道的可扩展速率域

On the Achievable Rate Regions for Interference Channels with Degraded Message Sets

Jinhua Jiang, Xin Yan

摘要:

具有降级消息集的干扰信道(IC-DMS)指的是这样的通信模型,其中两个MIMO尝试通过公共介质同时与它们各自的接收机通信,并且其中一个MIMO具有关于由另一个MIMO发送的消息的完整和先验(非因果)知识。一个编码方案,共同具有的优点,合作编码,协作编码,脏纸编码,开发这样的信道。借助于这种编码方案,在离散无记忆和高斯的情况下,IC-DMS的可实现的速率区域的推导,其中,在一般情况下,包括几个以前已知的速率区域。高斯情况下的数值例子表明,在高干扰增益制度,派生的可实现的速率区域提供了相当大的改进,这些现有的结果。

英文摘要:

The interference channel with degraded message sets (IC-DMS) refers to a communication model in which two senders attempt to communicate with their respective receivers simultaneously through a common medium, and one of the senders has complete and a priori (non-causal) knowledge about the message being transmitted by the other. A coding scheme that collectively has advantages of cooperative coding, collaborative coding, and dirty paper coding, is developed for such a channel. With resorting to this coding scheme, achievable rate regions of the IC-DMS in both discrete memoryless and Gaussian cases are derived, which, in general, include several previously known rate regions. Numerical examples for the Gaussian case demonstrate that in the high-interference-gain regime, the derived achievable rate regions offer considerable improvements over these existing results.
