ABSTRACT:
For encoding a source sequence of symbols (u) as an encoded sequence, the source sequence (u) is divided into p1first sub-sequences (Ui), p1being a positive integer, and each of the first sub-sequences (Ui) is encoded in a first circular convolutional encoding method. The source sequence (u) is interleaved into an interleaved sequence (u*), and the interleaved sequence (u*) is divided into p2second sub-sequences (U′i), p2being a positive integer. Each of the second sub-sequences (U′i) is encoded in a second circular convolutional encoding method. At least one of the integers p1and p2is strictly greater than 1 and at least one of the first sub-sequences (Ui) is not interleaved into any of the second sub-sequences (U′j).(It is noted that the above underlining of the following symbols is original, and is meant to be permanent:u,Ui,u*,U′i,U′j).
