中继通信容量的上限-部分I

Upper-Bounding the Capacity of Relay Communications - Part I

Farshad Shams, Marco Luise

摘要:

本文重点研究了点对点中继通信的容量,其中发送端由中间中继辅助。详细介绍了割集和放大转发(AF)保护策略的数学模型。从信息论的角度和高斯信道的网络中,我们提出了每种中继策略的容量上限。通过两个不同的案例研究,我们分析了所述策略的各种外部区域能力。结果表明,在低信噪比环境下,割集策略的性能优于放大和前向策略。

英文摘要:

This paper focuses on the capacity of point-to-point relay communications wherein the transmitter is assisted by an intermediate relay. We detail the mathematical model of cutset and amplify and forward (AF) relaying strategy. We present the upper bound capacity of each relaying strategy from information theory viewpoint and also in networks with Gaussian channels. We exemplify various outer region capacities of the addressed strategies with two different case studies. The results exhibit that in low signal-to-noise ratio (SNR) environments the cutset performance is better than amplify and forward strategy.
