摘要： In a satellite communication system a CDMA uplink signal including user data is transmitted in a packetized manner, the packets are switched on board the satellite by a packet switch before its downlink delivery. The packet switch routes the packets to the appropriate one of several outgoing downlink beams based on address information included in the packet header. Time Division Multiplexing (i.e., TDM) is used for downlink transmission. This invention constitutes an efficient multi-user satellite based communication system.

摘要翻译： 在卫星通信系统中，以分组方式发送包括用户数据的CDMA上行链路信号，在下行链路传送之前，分组在分组交换机上在卫星上切换。 分组交换机基于分组报头中包含的地址信息将分组路由到多个输出下行链路波束中适当的一个。 时分多路复用（即TDM）用于下行链路传输。 本发明构成了一种高效的基于多用户卫星的通信系统。
