Link design process 1. Define Requirements for each link 2. Design each Link Select frequency Select modulation coding apply antenna size beam width constraints Estimate atmospheric rain attenuation Estimate received noise, interference power Calculate required antenna gain transmitter power 3. Size the payload Payload antenna configuration, size mass Estimate transmitter mass power Estimate payload mass powerLink Design Process 1. Define Requirements for each link 2. Design Each Link – Select frequency – Select modulation & coding – Apply antenna size & beam width constraints – Estimate atmospheric, rain attenuation – Estimate received noise, interference power – Calculate required antenna gain & transmitter power 3. Size the Payload – Payload antenna configuration, size & mass – Estimate transmitter mass & power – Estimate payload mass & power
