半双工因果认知无线电信道的速率域研究

On Achievable Rate Regions for Half-Duplex Causal Cognitive Radio Channels

Debdeep Chatterjee, Tan F. Wong, Ozgur Oyman

摘要:

研究了认知源受半双工约束的因果认知无线电信道的编码问题。本文提出了一种考虑半双工约束的离散无记忆信道模型,并推导了该信道的一个新的可达速率域。证明了该速率区域包含了高斯信道下\cite{Devroye06}的因果可达速率区域。

英文摘要:

Coding for the causal cognitive radio channel, with the cognitive source subjected to a half-duplex constraint, is studied. A discrete memoryless channel model incorporating the half-duplex constraint is presented, and a new achievable rate region is derived for this channel. It is proved that this rate region contains the previously known causal achievable rate region of \cite{Devroye06} for Gaussian channels.
