| Abstract: | With help of ADS software tool, the OFDM system and SC - FDE system are implemented and simulated. Their structures and performances are compared. Their requirements for the lineafity of power amplifiers are analyzed. The simulation results show that the dual mode system based on the two systems will be the better broadband communication system. |
