Abstract :
The OFDM technology can conquer the frequency selected fading and the inter-channel interference (ICI) effectively, so it is the core technology in the future mobile communications. The basic principle and some key technologies of OFDM are studied in this paper. Then we gave the OFDM block diagram and simulink model. Under the non-ideal synchronization circumstance, we studied the signal changes before and after the channel estimation and synchronization. Verified the correctess of the model, and provided a platform for further study about the OFDM system.
