Intra-satellite Wireless Optical Network Communication Technologies and Implementation
|
Abstract:
The intra satellite wireless optical communication links provide the foundation for the intra satellite wireless optical network communication. For guaranteeing high quality of the links, the intra satellite noise immune technology, the intra satellite multipath immune technology and so on are crucial. The parameters of the intra satellite optical communication instruments, especially the weight, the size and the power consumption, must fit the satellite environment for implementing. The way to do research on the intra satellite wireless optical network communication is that to fuse the wireless optical network communication technologies and implementation into the satellite technologies and implementation. To utilize the unique characteristics of carrier running in the satellite environment is highly important too. The key components of the novel intra satellite wireless optical network communication technology are the intra satellite wireless optical adaptive encoding and modulating technology with the impulse waveform technology, the intra satellite wireless optical complex noise cancelling technology, the intra satellite wireless optical posterior equalization technology, the intra satellite wireless optical order trussing demodulating and decoding technology etc. All those must work in the satellite temperature with stress technology and so on. By implementing them, the intra satellite wireless optical system have stood the test for intra satellite wireless optical both one point to one point link and one point to multi points links. Furthermore, technologies of higher layers make the wireless optical network run high efficiently with high Quality of Service (QoS).
