Improvement of Concatenated Decoding Using Bit-Stuffing

Bit-stuffing is very known in digital communications and used for different purposes. This paper presents a novel algorithm which combines bit-stuffing with concatenated codes. SISO channel decoding is used as a mandatory part of a code concatenation, because of the soft or reliability values at its output. Reliability values of stuffed bits enable exceptional coding gain when used in a scope of concatenated codes and lot of possibility of combining with different coding schemes for various communication purposes, especially in video and audio communications. The paper presents a decoding algorithm using bit-stuffing and simulation results.
