基于USRP的变换域通信系统抗干扰平台实现

摘要

为验证TDCS系统的硬件可实现性及实际中良好的抗干扰性能,在变换域通信系统的基本原理及关键技术的基础上,通过搭建基于Labview+ USRP软件无线电变换域通信抗干扰实验平台的方法,阐述了收发机设计方法,初步测试了系统的抗干扰性能,并与直接序列扩频系统(DSSS)的抗干扰性能进行了对比.实验表明,TDCS系统较DSSS系统具有良好的抗干扰性能,具有硬件可实现性.%To test and verify the hardware realizability of TDCS system and the good antijamming performance in practice,on the basis of the basic principles of transformation domain communication system and the relevant key technologies,the authors expounds the method of transceiver design,conduct a preliminary test of the anti-jamming performance of the system,and compare its anti-jamming performance with that of direct sequence spread spectrum system (DSSS) by way of constructing Labview+USRP-based transformation domain communication anti-jamming software radio experiment platform.Experimental results show that,compared with DSSS system,TDCS system has good anti-jamming performance and hardware realizability.
