摘要
介绍了一种应用于抗干扰综合信息系统的数字扩频通信系统 ,具体讨论了利用匹配滤波器完成PN码的快速捕获和利用谱估计完成载频的频移补偿的数字化处理技术 ,系统可以实现远距离的无线数据通信 ,文中给出了中频数字部分的实现原理以及软硬件框图。
An anti-jamming DSSS Communication and its implementation are presented in this paper.The matched filter with FPGA implemented fast acquisition is discussed, the way of spectrum estimated to compensate carrier frequency shift is also discussed.The systems can be apply to remote wireless communication.The implemented principle of IF part and the structure of software and hardware are revealed in this paper.
