I have seen many implementations of a bch encoder/decoder but they go beyond what i think i need. We have a biometrics fingeprint system and are trying to just store the checkbits as the template. I was looking in java to just to code a simple bch or error correction code for encoding looking for errors and the decoding correcting those errors. A case of adding up values and then dividing but i am not sure what values?
thanks for any help
