BER Performance Analysis of Short Reference Differential Chaos Shift Keying Scheme Using Various Maps Over Different Channel Conditions

摘要

In this paper, design and development of chaos-based radio system are realized using short reference differential shift keying. In this communication system, the length of chaos reference sequence is reduced to R so that the message signal frame duration reduces as compared to former DCSK scheme. The proposed system is implemented on AWR-Virtual System Simulator (VSS) tool. VSS software is a comprehensive environment for the end-to-end design and system-level simulation of the communication system. With MATLAB co-simulation, we can readily import MATLAB code into VSS for enhanced system capability. The proposed system will be studied to deduce analytical BER expression under fading channel conditions and validated with simulated and experimental results.
