About Satellite communication links

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…
