慢衰落信道下的公共随机数产生

Common Randomness Generation over Slow Fading Channels

Rami Ezzine, Moritz Wiese, Christian Deppe, Holger Boche

摘要:

分析了在具有加性高斯白噪声(AWGN)和任意状态分布的单输入单输出(SISO)慢衰落信道中,相关离散信源在单向通信辅助下的公共随机性(CR)生成问题。慢衰落信道实际上与无线通信相关。我们完全解决了SISO慢衰落的情况下,通过建立相应的中断CR容量使用我们的表征其信道中断容量。所产生的CR可以被用来提高识别方案的性能增益。在许多新的应用中,后者被认为比经典的传输方案更有效,这些应用需要超可靠的低延迟通信。

英文摘要:

This paper analyzes the problem of common randomness (CR) generation from correlated discrete sources aided by unidirectional communication over Single-Input Single-Output (SISO) slow fading channels with additive white Gaussian noise (AWGN) and arbitrary state distribution. Slow fading channels are practically relevant for wireless communications. We completely solve the SISO slow fading case by establishing its corresponding outage CR capacity using our characterization of its channel outage capacity. The generated CR could be exploited to improve the performance gain in the identification scheme. The latter is known to be more efficient than the classical transmission scheme in many new applications, which demand ultra-reliable low latency communication.
