Based on analyzing the principles of meteor burst communications and the physical characteristics of meteor burst channel,according to the mechanism of using the signal frame as the basic transmission unit for adaptive variable rate transmission,the effects of the frame length on system performance are analyzed in this paper.According to the line electron density distribution of meteor bursts,the probability density function of the initial signal power received from the trails is derived.In terms of the function of the received signal power,the relationship between the system throughput and the frame length is built and the principle of frame length selection is determined.The simulation results show that the optimized frame length can maximize the average throughput of the system and make the best use of the meteor burst channel,while satisfying the reliability and instantaneity of the meteor burst communication system.
