Simulation and Verification of Anti-interference Performance of OFDM Systems

Orthogonal frequency division multiplexing is a multi carrier digital modulation technology that can maximize the utilization of spectrum resources. Starting from the principle of OFDM, this article uses MATLAB simulation to add noise to the signal and verify the difference between the emitted signal and the received signal, simulating the anti-interference performance of the OFDM system, thereby verifying the advantageous performance of the OFDM system.
