| Abstract: | This paper researched on the theory and coder structure of the RS code. The FPGA implementation of RS (255, 239) coder based on multiplication and addition in Galois Field is analyzed and discussed. An experimentation has been made using ALTERA's FPGA chip. At last, the result comparison and analyzation was given. This paper is very meaningful for the Error-Correcting Codes design based on FPGA. |
