MODELING OF SATELLITE COMMUNICATION LINKS WITH ORTHOGONAL FREQUENCY-DIVISION MULTIPLEXING / Kharchenko V.P., Wang Bo, Grekhov A.M., Leschenko A.M. // Transport. – 2016. – V.31. – №1. – P. 22–28.
Global technologies of data transmission in real time are developing constantly. Therefore modeling of messages transmission through satellite constellations is an actual problem. In this paper the original model of a communication channel "Vehicle-to-Satellite-to-Ground Station" based on principles of the IEEE 802.11a standard is designed using MATLABSіmulіnk software. The model allows simulating data transmission with data rate from 6 to 54 Mbit/s using adaptive modulation. For uplink/downlink two types of channels were analyzed - a free space path losses with phase/frequency offset and AWGN link. On the base of this model channel integrity was investigated and dependences of a signal-noiseratio (SNR) on free space path losses, antennas diameters, number of OFDM symbols and satellite transponder noise temperature were received. |
