Extending Cislunar Communication Network Reach Using Reconfigurable Intelligent Surfaces
arxiv(2024)
摘要
This study introduces a novel approach to enhance communication networks in
the cislunar space by leveraging Reconfigurable Intelligent Surfaces (RIS).
Using the ability of RIS to dynamically control electromagnetic waves, this
paper tackles the challenges of signal attenuation, directivity, and divergence
in cislunar missions, primarily caused by immense distances and that
Earth-based station transmitters do not always face the Moon. A new
optimization problem is formulated, whose objective is to maximize the received
signal-to-noise ratio (SNR) for Earth-to-Moon communications. We derive a
closed-form solution to the problem of determining the optimal RIS phase shift
configuration based on the effective area of the RIS. Through extensive
simulations, this paper demonstrates how optimal adjustments in RIS phase
shifts can significantly enhance signal integrity, hinting at the substantial
potential of RIS technology to revolutionize long-distance cislunar
communication.
