In order to study the related problems better, this paper examines the spread spectrum communication technology of MATLAB. In order to better master the technology, the Simulink software kit provided by Matlab is used to create a model called spread spectrum communication system. Then the simulation program is run and spread spectrum code is used to assure that the failure rate of the system does not change, so as to obtain the relationship between the spread spectrum gain and the output signal-to-noise ratio, and carry out academic research on the spread spectrum communication system. It has been found that the SNR output of the system has been improved. Therefore, through the study of the MATLAB simulation model, the spread spectrum communication system has a strong anti-jamming ability, which lays a concrete foundation for the modern communication of spread spectrum communication. technology of extended communication is complex and difficult to simulate. With the purpose o...
