| Abstract: | A high efficient transmission method of satellite relay link is presented to imp
rove the data transmission efficiency in airborne mobile communication. Voice d
ata is compressed
by changing the voice codec mode, and then is encapsulated into IP packet. Th
is high efficient transmission employs RTP(Real time Transport Protocol) multip
lexing and IP/UDP/RTP header compression scheme
to improve the transmission efficiency of the voice data. Finally, the performan
ce improvement by using the high efficient transmission method is investigated
through computer simulation. |
