Abstract

The method includes: determining a channel utilization rate and determining the minimum length of a data transmission frame length based on the determined channel credit rate; determining the maximum length of the data transmission frame length, and determining the optimal length of the data transmission frame length based on the maximum length of the data transmission frame length and the minimum length of the data transmission frame length, wherein the optimal length of the data transmission frame length is used for enabling the frequency utilization rate of data transmission to be the highest. Therefore, the data transmission frame length value range of the high-throughput satellite can be accurately and reasonably calculated, and the optimal data transmission frame length value is determined based on the optimal spectrum utilization rate, so that the data transmission frame length can be prolonged as far as possible, the guard interval can be reduced, and the spectrum utilization rate can be increased under the condition of inhibiting the error rate of the system.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a method, device and communication system for determining the frame length of satellite data transmission. Background technique [0002] With the expansion of urban areas, newly-built substations are located in remote areas, most of which are not covered by the operator's network. At the same time, the newly-built substations are not connected to the internal network of the power grid, so that the newly-built equipment cannot be connected to the main grid station for debugging. Therefore, it is generally necessary to provide a return path through the satellite to return the debugging data to the main station of the power grid. [0003] However, the traditional satellite communication method has low throughput, high packet loss rate, and poor stability, and cannot provide a stable large-bandwidth communication channel for equipment debugging in substations. A satellite c...
