两用户高斯衰落广播信道

The Two-User Gaussian Fading Broadcast Channel

Amin Jafarian, Sriram Vishwanath

摘要:

本文给出了两用户高斯衰落广播信道的外界。这些外边界是基于科斯塔的熵功率不等式(Costa-EPI),并制定数学上作为一个可行性问题。对于类的两个用户的高斯衰落广播信道的外界被发现有一个可行的解决方案,我们找到一个合适的内,外界满足的条件。对于所有这样的情况下,本文提供了高斯两用户衰落广播信道的容量区域的部分特征。

英文摘要:

This paper presents outerbounds for the two-user Gaussian fading broadcast channel. These outerbounds are based on Costa's entropy power inequality (Costa-EPI) and are formulated mathematically as a feasibility problem. For classes of the two-user Gaussian fading broadcast channel where the outerbound is found to have a feasible solution, we find conditions under which a suitable inner and outer bound meet. For all such cases, this paper provides a partial characterization of the capacity region of the Gaussian two-user fading broadcast channel.
