"基于MATLAB的跳频通信系统设计与仿真"

nt accurate and reliable information communication are crucial issues in the field of communication. Spread spectrum communication has rapidly developed in this context. Frequency hopping communication is one way of implementing spread spectrum communication, and it is a very good communication method in terms of anti-interference and security. In concrete implementation, frequency hopping communication involves the user's carrier wave randomly jumping according to a certain hopping pattern (pseudo-random hopping sequence) within a wide frequency band. Due to the uncertainty of frequency hopping, it achieves good communication security. In this graduation project, a fast frequency hopping communication system simulation is implemented using MATLAB. MATLAB is a powerful software that has been widely used in statistics, signal processing, artificial intelligence, and communication fields. In the design of the fast frequency hopping system, two main toolboxes, SIMULINK and COMMUNICATIONBLOCKS, are used. In the specific implementation process, programs written in MATLAB language are also used to design the entire process.
