Satellite-borne software processing transponder system and method for processing configuration information by using same

Abstract

The invention relates to a satellite-borne software processing transponder system and a method for processing configuration information by using the same. The system comprises a core control layer consisting of a core control unit, a channel management layer consisting of a plurality of channel interface units, and a channel processing layer consisting of a plurality of channel internal service processing units, wherein the functional layers and the composition units process the configuration information layer by layer according to a priority relation and an identity (ID) number identification mode until the configuration information is sent to a destination processing unit corresponding to an ID number, so that the functional reconfiguration process of a service processor is finished. A dedicated distribution processing channel for the configuration information is formed in the process that the satellite-borne software processing transponder system receives the configuration information from a dedicated channel and the final processing unit finishes reconstruction, but a service information processing channel of a processing transponder is not influenced.

Description

technical field [0001] The invention relates to a satellite-borne processing transponder system, which is especially suitable for communication satellites with processing and forwarding functions that need to implement software on-orbit reconfiguration processing. Background technique [0002] The on-board software processing transponder refers to the design idea of ​​software radio added to the on-board processing transponder function, so that the on-board processing transponder can realize dynamic on-orbit reconfiguration and loading of software according to business needs. On-board software-based processing transponder system, each channel and each processing unit are independent of each other and do not affect each other. As long as they are connected through a universal connector under the specified interface protocol, the expansion of channels and processing units can be realized. Different channels and processing units The unit can implement different communication sy...

Problems solved by technology

[0003] The existing research on software radio technology is mainly reflected in the functional reconfiguration of the main processor through the control of a dedicated control circuit. Hardware reconfigurable SDR platform", etc., the software radio platform mentioned in these documents constitutes as figure 1 , 2 As shown, from the perspective of the entire processing transponder system, there is only one layer of structure. This paper does not study how to process configuration information in the case of multi-processing channels and dedicated channel reception; the literature "Software Radio Layered Architecture", " A new structure of software radio station" and "Design and implementation of a completely reconfigurable soft radio" both mentioned a layered structure of software radio, such as image 3 As shown, a three-layer structure is adopted, which are: software radio interface layer, configuration layer and processing layer; it adopts the same processing path for configuration and service data streams, which are sent from the second layer to the third layer, which is Affects the processing of business information by the transponder

Also from image 3 It can be seen that the processing modules in the processing layer are connected, and each processing module in the processing layer performs pipeline processing on the received information. If the information to be processed belongs to the processing module, whether it is configuration or business information , this module will extract and process it, if it does not belong to this module, it will send the information to the next processing module; the pipeline processing process of each processing unit affects the speed of functional reconstruction of the processing unit
