中文摘要深空探测中的自主无线电主要作用是实现多个深空探测器间的通信,优点是能在未知无线电环境下不需要地面干预,自动实现无线电参数的识别和配置.阐述了自主无线电技术对深空探测的必要性.在与常规无线电技术、软件无线电技术比较的基础上,论述了深空探测中的自主无线电技术,分析了其必须解决未知无线电环境下参数估计这一关键问题.针对无线电参数估计目前存在的因果循环问题,提出了一种自主无线电技术参数估计迭代层次结构模型,分析了各层间的消息类型和迭代过程.
英文摘要The primary application of autonomous radio for deep space network is relaying commu-nication signals from multiple deep space assets. The advantage of an autonomous radio is that it can communicate to each asset that comes into view, automatically, without having to be reconfigured from Earth for each pass to account for differences in the signal characteristics. The autonomous ra-dio that can meet the need for deep space network is discussed. The fundamental difference between a conventional radio, or even a software-defined radio, and a truly autonomous radio for deep space network is that an autonomous radio has the ability to recognize features of an incoming signal with-out much a priori knowledge. Using conventional estimation and tracking design, one quickly gets into a chicken and egg problem. In this paper, we overview the architecture of an autonomous radio,define many parameters one might desire to estimate from the signal. Finally, an iterative layered architecture model of parameters estimating in the autonomous radio is presented, message-passing and the interaction of the estimators is analyzed.
