Abstract:
In this paper, a channel model on transport layer over Ka-band links is proposed, which apparently reflects the characteristics of rain attenuation and equivalent noise temperature from the earth’s atmosphere. The proposed model is built on a four-state Markov chain, which considered the different features of various packet types during CCSDS File Delivery Protocol (CFDP) transactions. We provide the exact criterion on how to divide different weather conditions at each state, and give the analytical results on transition probability matrix. In particular, we take Guangzhou in China as an example to find the probability distribution function of rain attenuation, and thus the transition matrix between different states, based on ITU-R rain attenuation model. The simulation results show that, compared with two state channel model, the proposed model could efficiently describe the error characteristics of different packet types during the file delivery, which leads to obvious degradations on CFDP performance.
