Method and apparatus for umbrella coding

摘要

A communication system and a method are provided. The communication system includes an encoder configured to encode source data and output an encoded frame including a mother code or a plurality of concatenated daughter codes based on an encoding option. The mother code and the plurality of concatenated daughter codes have a same number of coded data symbols. The mother code includes a first source number of source symbols and a first parity number of parity symbols. The daughter code includes fewer source symbols and fewer parity symbols than the mother code.

1. A communication system, comprising:
an encoder configured to encode source data and output, based on an encoding option, either: a) an encoded frame comprising a mother code having a first number of coded data symbols, or b) a plurality of concatenated daughter codes having a second number of coded data symbols; wherein: the first number of coded data symbols and the second number of coded data symbols are equal; the mother code comprises a first source number of source symbols and a first parity number of parity symbols; and the daughter code comprises fewer source symbols and fewer parity symbols than the mother code.
