OFDM (Orthogonal frequency-division multiplexing) is the key technology to 4G in the field of mobile communication. The theory of FH_OFDM and AFH_OFDM (Adaptive frequency hopping-Orthogonal frequency division multiplexing) systems is introduced firstly in this article, and the Simulink toolbox is used to set up the simulation model for AFH_OFDM system. In this paper, we compare the BER performance of FH_OFDM and OFDM systems in multi-path Rayleigh fading channel, and also compare the BER performance of AFH_OFDM system and FH_OFDM system in the condition of the broadband uniform noise and the bandlimited uniform noise. The simulation result shows that FH_OFDM system has a better BER performance than OFDM system in the condition of different interferences, and the BER performance of AFH_OFDM is better than FH_OFDM in the condition of the uniform noise.
