摘要
随着对适用于流星余迹信道的各种调制体制的日渐深入研究,基于流星余迹通信的调制方案也变得越来越复杂。为了达到流余系统通信性能进一步提高的目的,主要介绍一种基于流星余迹通信的调制解调器。介绍了流星余迹通信系统调制解调体制设计,探讨了调制解调器的具体设计及实现。给出了试验数据及测试分析,试验数据结果表明,该调制解调器完全满足系统指标,适应流星余迹信道的信道特性。
As the modulation methods adopted for meteor burst communication channel are more and more studied,the modulation schemes based on meteor burst communication become more and more complex.In order to improve the communication performance of meteor burst communication systems,a modem design applied in meteor burst communication is introduced.First,the design of modula-tion and demodulation schemes applicable to meteor burst communication is analyzed;then,the specific design and implementation of the modem are discussed.Finally,the test data and analysis results are provided.The test data indicates that the designed modem satis-fies the system specifications completely and is adapted to the characteristics of meteor burst communication channel.
