Joint Source-Channel Matching for Wireless Video Transmission

Wireless Video Transmission Leiming Qian, Douglas L Jones, Kannan Ramchandran and Swaroop Appadwedula January 18, 1999 Abstract With the rapid growth of multimedia content in wireless communication, there is an increasing demand for e cient image and video transmission schemes. In this paper we present a joint sourcechannel matching scheme for wireless video transmission. The scheme jointly optimizes the source and channel coder parameters to yield the optimal transmission quality. We utilize a parametric model approach, which avoids the necessity of having detailed a priori knowledge of the coders, thus making the scheme applicable to a wide variety of source and channel coder pairs. Our results show that the scheme yields excellent results and works for many di erent types of source and channel coder pairs.
