| 摘 要： | 在通用硬件系统的基础上,利用软件实现尽可能多的功能,便于系统改进和升级,使不同的系统间能够互联和兼容,提高系统性价比。从软件无线电基本理论出发,分析了信号的采样定理、多速率的处理理论和基于软件的数字调制和解调。以单信道发射机为例建立了基于软件无线电的数学模型,并分析研究了软件无线电在智能天线中的应用。对软件无线电存在的问题和发展前景做了论述。

| Abstract: | The software will realize more functions based on common hardware platform.It is convenient to improve the performance of the whole system,meanwhile,different systems can be interlinked and compatible.This paper analyzes the sampling theory,multi-rate signal processing theory and digital signal demodulation on basis of SDR.The mathematics model of the single channel transmitter is established,meanwhile,the primary application of SDR is also studied in smart antenna.Finally,this paper introuduces the exsiting problem and the future of SDR. |
