Guang Hui Cai, Shu Wen Zheng, Ping Li, Chuan Liang · Applied Mechanics and Materials · 2014
This paper introduces the basic principle of RS codes in OFDM system and the design method of 16 shift registers, finite field multiplicators and adders, on and timing circuit are validated by using of EDA tools Quartus II. Finally, the simulation results is given and demonstrates that a good channel encoding and decoding can be achieved by using FPGA in OFDM system, which can save the cost, shorten the designing cycle , and is convenient to speed up the listing of products, occupy less hardware resources, and comply with the development trend of modern communication.
