| Abstract: |
| Time delay is an important capability parameter of data link, and allo
cation arithmetic of timeslot has a great effect on this parameter. The model of
fixed allocation arithmetic of timeslot for Link16 is established by using que
ue theory. Time delay is analysed and discussed. Finally, Time delay is numeric
ally calculated and simulated. The results show that the fixed allocati
on arithmetic of timeslot is fit for the case that business volume is comparativ
ely steady and timeslot resource is enough. Choosing proper load rate can make s
ystem achieve favorable capability parameters. |
