However, the implementation of OFDM system requires complex signal processing algorithm and high performance digital signal processing (DSP) hardware. This paper introduces the opening report of the DSP hardware implementation and DA interface design of OFDM baseband transmission system. Firstly, the basic principles of OFDM technology and common modulation methods are introduced. Secondly, the signal processing process, hardware structure and circuit design of OFDM system are analyzed and discussed. Finally, a scheme of DA interface design and expected implementation effect are proposed, which provides reference and suggestions for subsequent research and design work.【Keywords】OFDM; DSP; signal processing; hardware implementation; DA interface design
