Line 7: Prior forms of [[Concatenated error correction code\|serial concatenated codes]] typically did not use recursive inner codes. Additionally, the constituent codes used in prior forms of serial concatenated codes were generally too complex for reasonable soft-in-soft-out ([[Soft-in soft-out decoder\|SISO]]) decoding. SISO decoding is considered essential for turbo decoding. Serial concatenated convolutional codes have not found ~~wide spread~~widespread commercial use, although they were proposed for communications standards such as [[DVB-S2]]. Nonetheless, the analysis of SCCCs has provided insight into the performance and bounds of all types of iterative decodable codes including [[turbo codes]] and [[LDPC]] codes.{{Citation needed\|date = June 2014}} US patent 6,023,783 covers some forms of SCCCs.
