| 摘 要： | 软件无线电的基本思想是将宽带A/D及D/A尽可能靠近天线,将无线电台的各种功能在一个开放性、模块化的通用硬件平台上尽可能多的用软件来实现。软件无线电已成为移动通信中的关键技术之一。文中基于软件无线电采用软件实现通用硬件调制的目的,通过基带信号处理算法,结合软件无线电接收机中的相关理论对其中的调制方式识别和解调算法进行了仿真,说明了各个解调模块的功能,而且也验证了系统的科学性和可实现性。

| Abstract: | The basic idea of software defined radio is making broadband A / D and D / A and the antenna as close as possible,and use the software to achieve radio function in an open,modular universal hardware platform as much as possible.The software radio has become one of the key technologies in mobile communication.This article uses the baseband signal processing algorithm,combined with the related theory in software radio receiver,carried out simulation about modulation recognition and demodulation algorithm,which illustrates function of various of demodulation module,and the system is validated by scientific and feasibility. |
