Multimedia transmission with improved reliability and efficiency for wireless communications

Abstract

In this paper, an efficient and reliable transmission system is proposed for multimedia transmission over mobile networks. In particular, multimedia data is represented in terms of its inherent correlation, and the transmission performance is characterized by transmission reliability and efficiency. Consequently, a joint source and channel coding scheme is devised in order to accomplish tradeoffs between transmission efficiency and reliability. Moreover, diversity reception is studied in terms of improved transmission reliability and reduced error protection. Numerical examples with both fixed and variable length coding algorithms are given to demonstrate that the proposed system performs very well under various operation conditions.
