  • Serial concatenation of interleaved convolutional codes forming turbo-like codes
    Patent number: 7421032
    Abstract: A serial concatenated coder includes an outer coder and an inner coder. The outer coder irregularly repeats bits in a data block according to a degree profile and scrambles the repeated bits. The scrambled and repeated bits are input to an inner coder, which has a rate substantially close to one.
