摘要:
A satellite communication system is disclosed which provides multiple beams and employs a plurality of user terminals (UT) and at least one gateway connected to a PSTN which communicates with at least one UT over the constellation wherein each of the UTs within a given frequency band is distinguished one from the other employing a combination of time slots and orthogonal codes.

摘要:
A multi-path device includes a plurality of communication paths being defined between a plurality of first transceivers and one second transceiver. Each communication path contains at least one repeater. Each signal transmission from the first transceiver to the second transceiver contains an identifiable copy of an identical signal copy over each communication path. There is a signal quality determining portion associated with the second transceiver for determining the quality of the signal copy received by the second transceiver via each of said communication paths. A communication path limiting portion controls the strength of each communication path based upon said signal quality determining portion. It is envisioned that this device may use a CDMA communication protocol.

An improved satellite communication system is provided comprising at least one satellite wherein each satellite provides multiple beams, a plurality of UTs, and at least one gateway connected to a PSTN and communicating with said at least one UT or with a constellation, wherein each of the UTs within a given frequency band is distinguished from another of the UTs employing a combination of TDM and NOPN codes and time slots.
摘要:
A satellite communication system is disclosed which provides at least one satellite employing multiple beams to a plurality of user terminals. A gateway is employed to connect to either a PSTN or an Internet communicating with the user terminal over the system so that the users within a given frequency range are distinguished one from the other employing orthogonal codes. The user terminal has the capability of either initiating or receiving packet data messages.
