| Abstract: | In order to meet the high-speed,wide-coverage,low-latency and high-reliability performance requirements of high-definition image transmission in the emergency field,the COFDM(Coded Orthogonal Frequency Division Multiplexing) technology is studied and analyzed,and the design scheme and application mode of a wireless video transmission system based on COFDM are proposed.The results of simulation experiments show that the proposed system can effectively improve the codec performance of wireless communication systems,and implement stable and reliable real-time transmission of high-definition images in complex wireless channel environments. |
