摘要
近年来,宽带、传输流量不对称的多媒体卫星系统的开发和应用,成为卫星通信的热点技术之一。介绍了一种Ka/Ku频段多媒体卫星系统的设计方案,描述了该系统的构成、应用,并对所涉及的调制解调、多址访问、网络接入、安全保密等关键技术进行了讨论。
In recent years, the development and application for multimedia satellite system, whose broadband and transmission flux are asymmetric, has become one of the hot techniques in the field of satellite communication.This paper introduces the design of Ka/Ku frequency band multimedia satellite system, which describes its structure, application and also discusses some key techniques concerning modem, multiple access, network access as well as its security, etc.
