Abstract

The invention discloses a satellite system communication method, device and system. The method comprises the steps that a base station carries out the downlink transmission of a synchronization signal, system broadcast information and corresponding control signal information in a mode of lower power density and wideband spread spectrum through employing the CDMA (code division multiple access) technology and a regional beam, and searches a currently usable spare frequency point of a high-speed business signal for transmission through employing the narrow-band FDMA (frequency division multipleaccess) technology. The system can coexist with other existing satellite mobile communication systems in a better way, and the broadband CDMA technology is used in the regional wave beam, thereby reducing the number of transmitting channels, and achieving a power-saving effect. The FDMA+TDMA technology is employed in a point wave beam, and all transmitting channels are switched off in an unoccupied service time gap, thereby achieving the power-saving effect.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of communication, and in particular, to a method, device and system for satellite system communication. Background technique [0002] Since satellite mobile communication is less affected by ground equipment and geographical environment, it is widely used in aerospace, ocean transportation, disaster prevention and mitigation, and special communications. However, the spectrum resources suitable for global satellite mobile communication are very limited. With the increase of satellite mobile communication demand, the contradiction of spectrum resource shortage has become increasingly prominent, and has even become the main bottleneck restricting the development of satellite mobile communication. The existing frequency bands suitable for carrying out satellite mobile communication services have basically been divided up by various satellite communication systems, and the development of new...
