Abstract
A desired coding rate is obtained by encoding source data to produce first additional data; randomizing the source data to produce randomized data; encoding the randomized data to produce second additional data; selecting a number of bits from the first and second additional data to produce first selected data and second selected data, the number of selected bits is selected based upon a data length of the source data and a desired data length of an output sequence; and multiplexing the source data with the first and second selected data. At least one of the data length of the source data and the data length of the output sequence is variable.
