Abstract
AbstractOptimization of system design parameters, such as onboard antenna diameter, number of beams, and number of onboard transponders, is of great importance to decide system capacity of subscribers in a multi‐beam mobile satellite communication system.This paper describes an optimization method of important system design parameters to maximize system capacity of subscribers under limited weight budget and dissipation power of satellite mission and limited service area.First, the concept of aquivalent weight, which is defined by a linear combination of weight and dissipation power of satellite mission is proposed. Next, the optimization of above design parameters, giving the maximum system capacity of subscribers, is made under the constant equivalent weight of the total satellite mission.As a result, it is found that the optimized conditions are simply expressed and universal.
