Syndrome generator block involves calculation of check bytes at the receiver side for the received data.
The computed check bytes are compared with the check bytes of the encoder scheme.The expression is Si=eCi xor dCi
eCi-encoded check byte
dCi-decode check byte
i-check byte number.
if S value is a zero element then no error exists.
If S value is non zero then an error has occurred in I th byte.
Check byte computation in encoder and decoder are the same
