| Abstract: | As a solution of multi-carrier digital communication,orthogonal frequency division multiplexing（OFDM） is the core technique in 4 G.The article introduces the fundamental principles of OFDM,devises a model of communication system of OFDM,and implements the dynamic simulation of the system using Simulink toolbox.From the simulation results,we can see that this system can reflect the performance characteristics of OFDM well.The simulation compares the BER of system under different two encoding methods of RS code and concatenated code,and finally we propose some further studying ideas about OFDM simulation system. |
