| Abstract: | A seheme is presented for OFDM digital signal and AM signal to transmit at the same band. The separation and carrier synchronization of OFDM signal is analysed, a solution is provided, and simulation is preformed. Simulation result shows that with this scheme, the digital signal and AM signal can be transmitted at the same band without interference on each other. |
