Abstract: A simplified method for decoding RScode capable of correcting two symbol errors is presented, based on solution toquadratic equation over finite field.Compared with conventional RS decoder, this method increases decoding speed and simplifies decoder structure.

Key words: block code, RS code, finite field, syndrom
