Uncoded Multimedia Transmission (pdf)

Description

This advantage makes uncoded transmission more suited to both unicast in varying channel conditions and multicast to heterogeneous users. In Part I of this book we consider how to improve the efficiency of uncoded transmission and make it on par with the coded transmission. In Part II, we discuss three technologies for multimedia correlation processing in uncoded transmission – Cactus, DCast and LineCast. All the three pieces of work demonstrate the possibility to build a more robust and efficient wireless multimedia communication system than existing digital ones. In fact, the efficiency of a transmission system is decided by how the resources, including bandwidth, power, and subchannel, are allocated. In Part III, we address the resource allocation problem for UVT in a Rayleigh fading channel, where only statistical channel state information (CSI) is available to the sender.
