A Frame Bandwidth Optimization Algorithm for Satellite Communication System

Abstract:
Satellite navigation systems have the characteristics of various transmission data types and complex service requirements. In order to solve the constraints of traditional frame generation algorithm on the multi-data transmission rate of satellite navigation system effectively, optimize the system frame bandwidth and reduce the probability of buffer overflow, in this paper, a variable window frame generation algorithm is designed to cater for having a better frame multiplexing efficiency, as well as, a packet arrival model is established, and the probability of buffer overflow and frame reuse efficiency is derived. Furtherly, the effectiveness of the algorithm is validated by simulation. The simulation results show that the window-variable frame generation algorithm can improve the frame transmission efficiency of the satellite navigation system effectively, compared with the traditional isochronous frame generation algorithm, it means that the new algorithm optimize the system frame bandwidth, and can provide a theoretical reference for future satellite communications.
