Modeling and simulation of RS and CCSK joint encoding and modulation based on Simulink

Spread spectrum and channel coding are two main anti-interference methods in wireless communication. In order to enhance the anti-interference ability of communication systems, this paper proposes a joint coding and modulation technology combining RS channel coding and CCSK. We have conducted research on the combination of RS encoding and CCSK modulation, with a focus on the research and Simulink programming implementation of CCSK demodulation algorithm based on FFT operation. The simulation results show that under the same channel interference conditions, the joint coding and modulation technology of RS and CCSK can effectively improve the system's anti-interference ability.
