基于FPGA的一种直接序列扩频信号接收技术

A Receiver of Direct Sequence Spread Signal Based on FPGA

在介绍了一种基于FPGA大规模可编程芯片的数字直接序列扩频接收技术的基础上,着重阐述了其数字接收机模型、PN码捕获及PN码同步技术,给出了该数字接收机的实际测量结果。

Direct Sequence Spread Spectrum technology has been used widely in both military and commercial communication. In this paper, a flexible DSSS digital receiver based FPGA was introduced. Some key technologies, such as the model of DSSS digital receiver, the PN code detection, the PN code tracking, were analyzed. At last, the measurement results were also showed.
