摘要

本文首次实现了基于差分混沌移位键控的混沌无线电实验系统。提出了基于软件定义无线电(SDR)的差分混沌移位键控(DCSK)实验系统的软件设计与实现，以实现实时无线传输。GNU Radio平台被用作我们实现的灵活的开源平台。为了在实时无线场景中执行，所提出的工作在接收端实现了同步单元。由于我们的系统是在SDR上，比特率、带宽和中心频率可以轻松修改。讨论了实验结果，并与理论预测结果进行了比较。最后讨论了实施过程中的一些趋势。

Implementation of a Differential Chaos Shift Keying communication system in GNU radio

In this paper the first experimental chaos radio system using Differential Chaos Shift Keying is realized. The software design and implementation are proposed for the experimental Differential Chaos Shift Keying (DCSK) system on software defined radio (SDR) to perform in a real-time wireless transmission. The GNU Radio platform is used as a flexible and open-source platform for our implementation. In order to perform in real-time wireless scenarios, the proposed work implements a synchronization unit on the receiver side. Since our system is on a SDR, the bitrate, bandwidth and central frequency can be modified at ease. The experimental performance are discussed and compared to the theoretical predictions. Finally some trends concerning implementation are discussed.
