18㎓ 무선 영상 전송을 위한 OFDM 송신기의 설계

The importance of broadband wireless communication implemented at subway tunnels is growing up. At 18㎓ wireless video transmission system, the transmitter requires a digital modulation method. At subway tunnel, A 18㎓'s influence of the multi-pass padding is strong. OFDM digital modulation that is strong for multi-pass padding is recommended. In this paper, Suitable to a subway wireless video transmission OFDM transmitter is designed. OFDM transmitter system is implemented by digital test board and RF test board.
