Control Theoretic Formulation of Capacity of Dynamic Electro Magnetic Channels

N. U. Ahmed, F. Rezaei, S. Loyka

摘要:

本文采用非齐次确定性和随机性麦克斯韦方程组严格地计算了波导(空腔、同轴电缆等)等电磁信道的容量。分布式,但本地化,和狄利克雷边界数据被认为是潜在的输入源。我们证明了存在的源措施,满足一定的二阶约束(相当于功率约束),在该信道容量达到。进一步给出了最优性的充分必要条件。

英文摘要:

In this paper nonhomogeneous deterministic and stochastic Maxwell equations are used to rigorously formulate the capacity of electromagnetic channels such as wave guides (cavities, coaxial cables etc). Both distributed, but localized, and Dirichlet boundary data are considered as the potential input sources. We prove the existence of a source measure, satisfying certain second order constraints (equivalent to power constraints), at which the channel capacity is attained. Further, necessary and sufficient conditions for optimality are presented.
