The code rate (or information rate) is a fractional number that expresses what part of the redundant message is actually meaningful. For instance an encoder with 1/3 rate will output 3 bits of message for each bit of data. Therefore, bigger code rates produce stronger codes.
Currently, only decoders of the 1/n form can be generated (Punctured codes are not supported). Furthermore, the web version of the generator will only accept n smaller or equal to 6. To generate codes outside this range, please contact us.
