摘要/Abstract

摘要： 本文给出卫星转发器在不同载波数下三阶交调总载交功率比的递推公式,从而,提出程序计算最佳工作点的方法.作为应用,本文给出不同的卫星通讯参数下最佳工作点的工程设计图.该图能使总体设计师们从繁杂的计算中解脱出来.文中的例子为便于验证和仿用.

Abstract: In this paper, a few recurrence formulas of the three-order mnltioarrier/total intermodulation-power ratio for different number of carriers through a satellite communication transponder are given.
Thus, a programme-calculated method for the optimum operation point is put forward. Some engineering design charts under the condition of different parameters of satellite communications are given. By means of the charts, the designers of the overall system can focus their attention tin analysis and comparison without being involved in complicated calculations.
Some examples are given for confirmation and application.
