Methodology for the design¶

In order to fulfil the requirements, we have developed a methodology in three steps:

• Evaluation of the required Modulation and Coding (MOCOD)
• Estimation of the required Eb/N0 for this MODCOD
• Computation of the (G/T) of the ISAE receiver required to cope with this Eb/N0

Then, from the (G/T) value, we can discuss about the type of antenna that can be used for the ISAE receiver according to the constraints developed in "constraints for antennas selection".
