ABSTRACT:
A method apparatus for encoding segments having a selected number of ordered bits of binary data from a sequence of ordered bits of binary data into corresponding codewords having a selected number of ordered bits of binary data, such that the sequence of ordered bits of binary data is encoded into a sequence of codewords. The apparatus comprises a receiver device for receiving the segments; a separating device for separating the selected number of ordered bits of binary data of each segment into a corresponding first group and a corresponding second group; an encoder mapping device for mapping each first group into a corresponding word having a selected number of ordered bits of binary data; and an interleaving device for interleaving the bits of each corresponding second group with the selected number of ordered bits of binary data of each corresponding word to obtain the corresponding codewords.
