Abstract

Previous studies highlighted the importance of using residual redundancy techniques in the design of a joint source channel decoder for the case of data transmission over binary symmetrical channel. This paper uses the sequence maximum a posteriori (MAP) method, which is one of the residual redundancy techniques to design a joint source channel coding with the representation of the wireless communication channel by the Gilbert-Elliott channel (GEC). The paper also discusses the issue of parameters estimation for the GEC channel. A new modification is suggested to the Baum-Welch re-estimation technique in order to improve its performance and reduces its computational requirements.
