|---|---|
| One of the available propagation impairment mitigation techniques (the methods used to counteract the adverse effects to the signal in the satellite communication channel) is time diversity (TD). This technique relies in resending the information a conveniently chosen time after, in order to obtain a diversity gain when a fade event occurs. TD analysis can be carried out when experiments with high availability and for a relatively long period of time are available. Since the GTIC-Radiocommunication Research Group has excess attenuation data with very high availability (higher than 97 %) collected from two satellite beacon receivers, one receiving the 20 GHz signal coming from KA-SAT and the other receiving the 40 GHz signal coming from Alphasat, for a four-year period, a TD analysis have been carried out, and it is presented here. Results are also compared with four available models: Matriccini, Joint Probability, Greece and ONERA, giving very good approximations for both bands. | |
