Description
Technical field
This utility model relates to technical field of satellite communication, is specifically related to a kind of satellite communication network management system based on FTN transmission.
Background technology
FTN (Faster-than-NyquistSignaling) is a kind of time domain non orthogonal transmissions mode, i.e. uses the mode carrying out signal transmission higher than the speed of Nyquist criterion defined.Theoretical proof, FTN transmission means has bigger shannon capacity than traditional Nyquist system.FTN provides a kind of spectral efficient transmission means that can substitute high-order QAM modulation, and the non-linear distortion for channel has higher robustness；FTN can change spectrum efficiency by adjusting the time domain data compression factor, thus realizes adaptive coding and modulating flexibly；When FTN with MIMO is combined, it is possible to utilize excess bandwidth, promote further mimo system up to spectrum efficiency.
Consider to apply in the nonlinear satellite channel mainly caused FTN by high power amplifier.Compared to existing satellite communication system, on the one hand, FTN can adjust spectrum efficiency flexibly by the compressibility factor changing time domain and frequency domain, also is able to realize higher spectrum efficiency simultaneously.Its way is by the way of relatively-stationary coding with FTN cascade, can be relatively easy to realize adaptive coding and modulating on the basis of the exponent number not changing planisphere and coded system.On the other hand needing the factor considered is that high order modulation is to increase spectrum efficiency by the quantity increasing constellation point, and FTN is then to increase spectrum efficiency by time domain data compression；When both are when obtaining same spectrum efficiency, the non-linear impact on high-order QAM modulation is more than the impact on FTN signal.Therefore, avoided the use of the planisphere modulation system of high-order by FTN technology, thus reduce the nonlinear channel impact on distorted signals.
In VSAT system is applied, there is each plant equipment self-organizing system of network management function, incompatible, lacking versatility, the heart is by network management control channel and remote monitoring equipment UNICOM, for improving the utilization rate of satellite resource, for data collecting system, need a good management system.
