A system optimization approach to FDMA loadings

The author investigates an approach to maximize frequency division multiple access (FDMA) transponder performance by simultaneously optimizing transponder gain and operating point and uplink signal powers under the assumption that the system is not bandwidth limited. The methodology used, including the assumptions and approximations made, is described. The detailed analysis with a derivation of the equations for required uplink effective isotropic radiated power are presented. An example is included to illustrate the concepts presented
