Models, Statistics, and Rates of Binary Correlated Sources
摘要:
本文讨论和分析了各种模型的二进制相关源,这可能是相关的几个分布式通信方案。这些模型的统计特征在于联合概率质量函数(PMF)和协方差。还给出了源的联合熵的封闭形式的表达式。大量的源的渐近熵率收敛到一个共同的限制,所有考虑的模型。这一事实概括了最近的结果信息理论的性能限制的通信计划,利用在接收机的源之间的相关性。
英文摘要:
This paper discusses and analyzes various models of binary correlated sources, which may be relevant in several distributed communication scenarios. These models are statistically characterized in terms of joint Probability Mass Function (PMF) and covariance. Closed-form expressions for the joint entropy of the sources are also presented. The asymptotic entropy rate for very large number of sources is shown to converge to a common limit for all the considered models. This fact generalizes recent results on the information-theoretic performance limit of communication schemes which exploit the correlation among sources at the receiver.
