Detailed Explanation of The Concept of Antenna And Related Important Parameters
Satellite communication links design aim:
1. Get corresponding communication reliability(BER value, S/N value) when Transmission Power and receiving antenna diameter are as low as possible;
2. Provide design reference for key components of RF system(such as HPA,LNA), and provide design aim for antenna system;
3. Consider the links attenuation under various condition and provide available link allowance.
The picture below is the uplink and downlink power variation of satellite communication system:
