Abstract
For encoding a source sequence of symbols () as an encoded sequence, the source sequence () is divided into pfirst sub-sequences (), pbeing a positive integer, and each of the first sub-sequences () is encoded in a first circular convolutional encoding method. The source sequence () is interleaved into an interleaved sequence (*), and the interleaved sequence (*) is divided into psecond sub-sequences ('), pbeing a positive integer. Each of the second sub-sequences (′) is encoded in a second circular convolutional encoding method. At least one of the integers pand pis strictly greater than 1 and at least one of the first sub-sequences () is not interleaved into any of the second sub-sequences (′). (It is noted that the above underlining of the following symbols is original, and is meant to be permanent:,,*,′,′).
