Problems solved by technology

However, at present, digital flexible forwarding can only realize signal exchange between different beams, and does not support the signal merging function between beams, and cannot realize multi-system cross-beam networking communication. In addition, the hardware architecture needs to use an additional high-speed processing clock that is more than twice the data clock. Or it can only be achieved by using a parallel processing architecture. The use of high-speed clocks will affect the stability of the system and increase the power consumption of the device. Using a parallel processing architecture will greatly increase the occupation of hardware resources. Poor scene adaptability

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as figure 1 As shown, a digital flexible forwarding device includes multiple analog-to-digital conversion modules, R analysis part filter modules, R IDFT (inverse discrete Fourier transform) modules, enhanced large-capacity high-speed switching modules, R DFT (discrete Fourier transform) module, R integrated partial filter modules and R digital-to-analog conversion modules, where R is a positive integer. The analysis part and the synthesis part filtering module both include a data memory with M rows and N columns and a coefficient memory with M rows and N columns, and both M and N are positive integers;

[0033] The analog-to-digital conversion module performs analog-to-digital conversion on the uplink beam signal according to the data clock, obtains the input data of the beam, and sends it to the data memory of the filte...

Abstract

The invention discloses a digital flexible forwarding method and device, and relates to digital flexible forwarding technology in the field of satellite communication. The present invention transforms the existing implementation architecture, can realize multi-system cross-beam networking communication, and adopts the centralized storage method of input data at the same time, which can reduce the occupation of hardware resources compared with the existing multiple memory storage methods, and can adopt the same method as the data clock The implementation of the same low-speed processing clock has low requirements on software timing, which helps to improve system operation stability and reduce device power consumption, and has strong adaptability to on-board flexible forwarding application scenarios.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a digital flexible forwarding method and device. Background technique [0002] Digital flexible forwarding can realize the flexible exchange of signals between different beams. With the development of multi-beam satellites, the application of digital flexible forwarding becomes more and more frequent. However, at present, digital flexible forwarding can only realize signal exchange between different beams, and does not support the signal merging function between beams, and cannot realize multi-system cross-beam networking communication. In addition, the hardware architecture needs to use an additional high-speed processing clock that is more than twice the data clock. Or it can only be achieved by using a parallel processing architecture. The use of high-speed clocks will affect the stability of the system and increase the power consumption of the device. Using a parallel p...
