| 摘 要： | 卫星通信中准确而方便地计算交调干扰对颖分多址(FDMA)有巨大的实际意义。特别对一个转发器中有很多载波的单路单载波系统(SCPC)来说,这种计算显得更为重要。本文利用贝塞尔级数法对多电平SCPC系统的交调作了分析,并在DPS-8机(Fortran语言)和王安MVP-2200机(BASIC语言)上进行了实例计算,为某气象卫星转发器中的SCPC载波的功率和频率设计提供了有用的结论。限于篇幅,程序清单从略,仅列出主要框图和计算结果。

| Abstract: | It is important to calculate the intermodulation (IM) interference for FDMA in satellite communications. It is more so for the SCPC system because there are more carries in it. This paper makes an analysis of IM interference for SCPC with the help of Bessel series and describes the practical calculations by using computer DPS-8 in FORTRAM language and Wang MVP-2200 in BASIC language for the power and frequency design of a meteorological satellite transponder in a 5--level SCPC system. As space is limited, it is impossible to publish the list of programmes in full. Only the main flow charts and computed results are given here. |
