Optimum transponder gain and power for fully loaded satellite

This correspondence derives expressions for the total satellite transponder power, transponder gain, and all the terminals' transmit links power taking into account all of the system parameters such as uplink and downlink satellite antenna gains, the ground terminals' receive gain and noise temperature, path losses and fades, data rates, required Eb over No, etc. Both orthogonal waveforms as well as self-interfering waveforms such as pseudonoise spread spectrum in presence of jamming are included.
