The way of construction of casual codes of the big length is submitted on the basis of recursive convolution codes at use of parallel cascade code designs of type turbo codes. Turbokod is the good method of construction of casual code of large length. Main principle of code of turbokodis the use of two (or more) parallel workings elementary coder. Thus an informative block is encoded twice, thus the second time – after previous transposition.
