半双工高斯协作干扰信道的容量界

Capacity Bounds of Half-Duplex Gaussian Cooperative Interference Channel

Yong Peng, Dinesh Rajan

摘要:

本文研究了两用户高斯干扰信道下的半双工协作通信方案。我们开发的情况下,当系统允许发射机或接收机合作的可实现的区域和外边界。我们表明,通过使用我们的发射机合作计划,有显着的容量改善相比,以前的结果,特别是当合作链路是强的。此外,如果合作信道增益是无穷大,我们的发射机和接收机的合作率达到各自的外边界。它还表明,发射机合作提供更大的可实现的区域比接收机合作在相同的信道和功率条件下。

英文摘要:

In this paper, we investigate the half-duplex cooperative communication scheme of a two user Gaussian interference channel. We develop achievable region and outer bound for the case when the system allow either transmitter or receiver cooperation. We show that by using our transmitter cooperation scheme, there is significant capacity improvement compare to the previous results, especially when the cooperation link is strong. Further, if the cooperation channel gain is infinity, both our transmitter and receiver cooperation rates achieve their respective outer bound. It is also shown that transmitter cooperation provides larger achievable region than receiver cooperation under the same channel and power conditions.
