A Complete Reed-Solomon Encoding and Decoding Example

By Hugo Lyppens

Dr. Dobb's Journal January 1997 

(x<sup>4</sup> + x<sup>2</sup>)  *  (x<sup>2</sup> + 1) = (x<sup>6</sup> + x<sup>2</sup>)x<sup>8</sup> = x<sup>6</sup> + x<sup>5</sup> + x<sup>4</sup> +1x<sup>255</sup> = x<sup>0</sup> = 1

Example 2: Multiplication in GF(28) is done modulo f (x)= x8 + x6 + x5 + x4 + 1.
