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.
