Abstract
An adaptive Reed-Solomon(RS) decoder (207) and analogous methods arranged and constructed to decode a RS(n,k) encoded symbol stream, including; a code register (211), coupled to the symbol stream, for storing a received code word including code symbols, an index register (213) for storing a location information corresponding to each of a portion of the code symbols, a processor (215), coupled to the code register (211) and the index register (213), for performing soft decision decoding using an error parameter (217) and an erasure parameter (219) to provide corrected data (215) when the decoding is successful and to provide a failure indication (221) when decoding is unsuccessful, and a controller (223), coupled to the processor (215), for providing the error parameter and the erasure parameter and for adjusting the error parameter and the erasure parameter when the processor provides the failure indication.
