18GHz 무선 영상 전송을 위한 OFDM 송신기의 설계

초록

The importance of broadband wireless communication implemented at subway tunnels is growing up. At 18GHz wireless video transmission system, the transmitter requires a digital modulation method. At subway tunnel, A 18GHz'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.
