Although a simple concatenation scheme was implemented already for the 1971 [[Mariner]] Mars orbiter mission,<ref name="McEliece"/> concatenated codes were starting to be regularly used for [[Deep Space Network|deep space]] communication with the [[Voyager program]], which launched their first probe in 1977.<ref name="deep-space-codes">K. Andrews et al., ''The Development of Turbo and LDPC Codes for Deep-Space Applications'', Proceedings of the IEEE, Vol. 95, No. 11, Nov. 2007.</ref> Since then, concatenated codes became the workhorse for efficient error correction coding, and stayed so at least until the invention of [[turbo codes]] and [[LDPC codes]].<ref name="McEliece"/><ref name="deep-space-codes"/>

Typically, the inner code is not a block code but a [[Soft-decision decoder|soft-decision]] [[convolutional code|convolutional]] [[Viterbi decoder|Viterbi-decoded]] code with a short constraint length.<ref name="Odenwalder">
