The purpose of adaptive frame length transmission for an advanced orbiting system(AOS) is improving its throughput.With this in view,a series of specific arithmetic is proposed,such as the arithmetic for packet channel multiplexing,for virtual channel(VC) multiplexing and for frame synchronization.The arithmetic of packet channel and VC multiplexing purposes to meet the needs for generating and transmitting adaptive length frames,reduce delay time,and improve multiplexing efficiency.The frame synchronization arithmetic is to avoid the bit error influence of frame length markers,enhance the probability of frame synchronization and improve the reliability of data processing.The performance formulas of the new arithmetic are given and analyzed to obtain the relevant parameters used in the simulation of the throughput performance,which shows that the proposed arithmetic is suitable for AOS adaptive frame length systems and it can effectively ensure outstanding system throughput.
