The Research on Packets Multiplexing Efficiency Based on AOS Space Data Link Protocol

The MPDU multiplexing was taken as the first phase of the multiplexing mechanism of CCSDS, whose efficiency was bound up with transmission performance and capability of valid data on advanced orbiting systems. Based on model of forming frame with Poisson distribution and invariable packet and slot, the concept of high order of residual function was presented and the formula of MPDU multiplexing efficiency was given. The simulation results showed that the experimental simulation validated the theoretical curves very well with the higher order of residual function.
