摘要

美国国防部(DoD)正在开发一种移动用户目标系统(MUOS)。这种下一代卫星系统将为地面、机载和舰载用户提供语音和数据服务,特别强调为大量手持用户提供服务。MUOS体系结构的一个主要元素可能是国防部拥有和操作的卫星系统,该系统使用当前UHF MILSATCOM频段。本文概述了一种国防部超高频卫星系统的创新架构,该系统为包括手持设备在内的各种用户类型提供大量的系统范围容量和可靠的服务。特别是,该系统在面对该频段历史上遇到的严重信道损伤时具有鲁棒性。该体系结构的关键属性是具有多样性组合的路径多样性。描述了总体多样性组合体系结构,并给出了性能估计。

A robust satellite system architecture for the mobile user objective system
The Department of Defense (DoD) is pursuing development of a mobile user objective system (MUOS). This next generation satellite system will provide voice and data services to ground, airborne and shipborne users with special emphasis on serving a large population of handheld subscribers. A major element of the MUOS architecture will likely be a DoD owned and operated satellite system in the current UHF MILSATCOM frequency band. This paper outlines an innovative architecture for a DoD UHF satellite system which provides substantial system wide capacity and reliable service to a wide range of subscriber types, including handhelds. In particular, the system is robust in the face of the severe channel impairments historically encountered in this band. The key attribute of the architecture that enables handling the impairments is path diversity with diversity combining. The overall diversity combining architecture is described and performance estimates are presented.
