软件无线电中的信道化技术研究

Research on channelized technology in software radio

软件无线电通信利用多频段和多模式的无线通信进行互连互通,具有极大的灵活性和适应性。文章围绕无线电接收机的信道化技术、带通采样理论等展开论述,利用CIC,HBF和FIR级联设计下变频抽取系统的实际方案作为论据,对基于软件无线电技术的信道化技术等展开论述,探讨软件无线电多速率信号等处理技术要点。

That software radio communication using wireless communication of multiple frequencies and modes of interconnection to carry out mutual communication, enjoys great flexibility and adaptability. This paper carries out the discussion around channel technology, sample theory of radio receiver, makes use of CIC, HBF and FIR practical scheme based on cascaded inverter design as the argument to discuss the channel technology based on software radio technology, and explore the key point of software multiple rate signal processing technology.
