Why Is Reed-solomon Better Than Bch


How many errors can Reed-Solomon correct?

16 symbol errors
A Reed-Solomon decoder can correct up to t symbols that contain errors in a codeword, where 2t = n-k. The decoder can correct any 16 symbol errors in the code word: i.e. errors in up to 16 bytes anywhere in the codeword can be automatically corrected.

How does Reed-Solomon work?

Reed–Solomon codes are able to detect and correct multiple symbol errors. By adding t = n − k check symbols to the data, a Reed–Solomon code can detect (but not correct) any combination of up to t erroneous symbols, or locate and correct up to ⌊t/2⌋ erroneous symbols at unknown locations.

What are BCH and RS codes?

The RS code is a subset of the BCH code. The coding process of the BCH is simple to implement. The decoding process of the BCH codes is relatively simple. The RS code is more suitable for concatenated codes.

How do you use the Reed-Solomon code?

In Reed-Solomon codes, message size is given by (n-2t) where t= number of errors corrected. Parity check size is given by = (n-k) or 2t symbols. Minimum distance(a) is given by = (2t+1).
