Abstract

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.
