Design and Implementation of an OFDM System with Interleaving and De-Interleaving Based on FPGA

Abstract:

Today's wireless communication has become the primary means of communication, the wireless communication relative to wired communications, its random parameter channel delay problem and fading problem raising a new challenge to the reliability of communication. This article describes the basic principle of OFDM system with interleaving and de-interleaving, Verification platform to build on this basis, and using EDA tools Quartus II functional and timing verify the correctness, Giving the integrated circuit simulation results, also showing the use of FPGA to achieve interleave and interleaving process well in OFDM systems. Effectively improve the reliability of the system, not only meet the needs of Systems on flexibility and real-time, but also occupy less hardware resources, fast, and consistent with the development trend of modern communications.
