| 摘 要： | 软件无线电的基本思想是构造一个具有开放性、标准化、模块化的通用硬件平台,通过软件编程来实现无线电台的各种功能。调制方式的多样化必然导致无线电台的多模式化。调制方式多样化的存在,就必须要具备自动识别各种调制方式的方法,所以,信号调制方式的自动识别是软件无线电中必须具备的功能之一。决策理论具有结构简单,识别种类多的优点,这也是本文采用决策理论的主要原因。最后仿真验证了决策理论是非常有效的。

| Abstract: | The basic idea of Software Defined Radio(SDR) is to construct a general hardware platform with openness,standardization and modularization and implement all kinds of function of SDR by software programming. The diversity of signal modulation must lead to multi-modes of radio. The existence of diversity of modulation must have methods for automatic recognition of multiple modulation modes. So,the automatic recognition of multiple signal modulation modes is one of key technologies for SDR. Decision theory has... |
