【Abstract】 Based on the principles of OFDM, key technology (Encoding and decoding, synchronization, equalization), and the current transmission system is learnt. Particularly discusses the key technology and its implementation process in detail. On this basis completely based on OFDM transmission of system is designed. In order to meet our performance requirements for the system, we highlight several important part of the transmission system. Modem design, the modem implementation, transmission bus controller design, interface design. Finally, by the analysis of data transmission systems verifies the practical value of the system, and gives directions for further research.更多还原
