Interleaver (Π): Generate a different information sequence (a permuted sequence) as the input to the RSC encoder (2). Normally, it is a random interleaver.

In naval applications, the information is mostly sent through wireless networks and the data is more prone to noise. Turbo codes
Turbo codes are a class of error correcting codes codes introduced in 1993 that come closer to approaching Shannon’s limit than any other class of error correcting codes.
Turbo codes achieve their remarkable performance with relatively low complexity encoding and decoding algorithms.

We call these systems “turbo-like” codes and they include as special cases both the classical turbo codes [1,2,3] and the serial concatentation of interleaved convolutional codes [4]. We offer a general conjecture about the Natural Sciences and Information Technologies at the University of Primorska. It is not possible to cover here in detail every aspect of cyclic codes, but I hope to provide the reader with an insight into the essence of the cyclic codes.
