Abstract:
1. A method, comprising: receiving a sequence of data in a cable modem system; splitting the sequence of data into a sequence of pre-encoded data and a sequence of unencoded data; encoding the sequence of pre-encoded data using an outer encoding algorithm to provide a sequence of outer encoded data; encoding the sequence of outer encoded data using a Low Density Parity Check (LDPC) Code to provide a first sequence of encoded data; combining a first bit increment from the sequence of unencoded data and a second bit increment from the first sequence of encoded data to provide a second sequence of encoded data; segmenting the second sequence of encoded data into a plurality of symbol labels; and assigning to each symbol label from among the plurality of symbol labels a corresponding modulation symbol in accordance with a specific mapping scheme, wherein the separating, encoding, combining, segmenting and assigning are performed by one or more communication devices.
