完整的软件无线电（SoftwareRadio）概念和结构体系是由美国的Joe．Mitola首次于1992年5月明确提出的。其基本思想是：将宽带A／D变换尽可能地靠近射频天线，即尽可能早地将接收到的模拟海号数字化，最大程度地通过软件实现电台的各种功能。通过运行不同的算法，软件无线电可以
The complete software radio (SoftwareRadio) concept and structure of the system by the United States Joe. Mitola was first explicitly stated in May 1992. Its basic idea is: Broadband A / D conversion as close as possible to the RF antenna, that is, as early as possible to digitize the received analog sea, the maximum extent possible through software to achieve the radio’s various functions. By running different algorithms, software radios can
