本文讨论了对遥感、遥测多路信息的可靠传输问题,分析了多个付载波窄带调相系统中各付载波之间产生的互调情况。叙述了确定各路信息带宽的方法;并根据各路不同信息带宽的要求,设计了用计算机算出具有K个付载波的调相系统中各频率分量的流程图;并附有三个及七个付载波的计算实例。
This paper discusses the reliable transmission of multi-channel remote sensing and telemetry information, and analyzes the intermodulation conditions of each subcarrier in multiple subcarrier phase modulation systems. The method of determining the information bandwidth of each channel is described. According to the requirement of different information bandwidth of each channel, a flow chart of calculating each frequency component of the phase modulation system with K subcarriers by computer is designed. Three and seven Carrier Calculation Example.
