1.To improve the reliability of communication, the rule of point-to-point error control and the addition of a byte of check sum are introduced into the system.
2.EPON technology is developed based on Ethernet , the main new feature in EPON system is the control of pointto multi - point , so this article focuses on the multi - pointcontrol information of EPON including MPCP , P2PE and so on .
3.Based on MC35 module, this design realizes the GPRS function and the communication of peer to peer through embedding PPP(Point-to-Point Protocol),TCP/IP(Transfer Control Protocol/Internet Protocol) in SCM(Single Chip Micyoco).
6.SHD-A model transmitter is applied to emit and convey baseband signal of sound, vibration and measure-control in aeronautical communication system from one pointto mul-ti-point.
