Line 20: The description above is given for what is now called a serially concatenated code. [[Turbo code]]s, as described first in 1993, implemented a parallel concatenation of two convolutional codes, with an interleaver between the two codes and an iterative decoder that would pass information forth and back between the codes.<ref name="deep-space-codes"/> This construction had much higher performance than all previously conveived concatenated codes. However, a key aspect of turbo codes is their iterated decoding approach. Iterated decoding is now also applied to serial concatenations in order to achieve higher coding gains. == ~~References~~Notes == <references/> == References == * {{cite book \| author=F.J.
