Abstract :
The Channel estimation is one of the key technologies in OFDM receiving system. Which will directly affect the transmission quality of communication systems. This paper, based on the analysis of the characteristic of Ka-band satellite-ground link Channel, and comprehensive consideration of the impact of free space, attenuation , rainfall and so on, to the communication system, the Satellite-Ground link channel model of OFDM System is established, then a method of channel estimation based on the channel model is put forward. Simulation result shows that the method have lower complexity and higher performance.
