Combining spectral shaping with turbo coding in a channel coding system

摘要

A method of combining spectral shaping with turbo coding in a channel coding system. The method comprises encoding user data with spectrally shaped encoding to provide a suppressed DC user data sector output. The method also comprises generating turbo coded redundant bits for the suppressed DC user data sector. The turbo coded redundant bits are interleaved with additive coding to provide a suppressed DC parity sector.
