基于软件无线电的多体制遥测调制方法研究

摘要

目前国内的遥测应用主要以PCM/FM主,随着遥测数据量的增加,这种方法已无法满足未来空空导弹遥测的需求.提出了一种新型的调制方法,通过对比,可以看出,它既不同于PCM/FM,也不同于MSK和SOQPSK,但却具有后者的优点.在实现上,却并不此后者复杂,因此,具有很好的应用前景.由于软件无线电方法本质上是一种数字实现,对于国内遥测数字化实现有着很好的理论参考价值.%At present, PCM/FM is mainly used in the telemetering applications, with the increase of the data rate, this method is unable to meet the needs of the future missile telemetry. This paper presented a new modulation method, by contrast,could be seen. It was different from the PCM / FM,was also different from the MSK and SOQPSK. However, it had the advantages of the latter. In implementation, but not more complicated than the latter, therefore, had a good prospect of application. As the software radio approach was essentially a digital implementation, had a good theoretical reference value for domestic telemetry .
