Bandwidth-Efficient Wireless Multimedia Communications: Problems Solutions and Challenges
Bandwidth-Efficient Wireless Multimedia Communications: Problems Solutions and Challenges
Commencing with the brief history of mobile communications and the portrayal of the basic concept of wireless multimedia communications, the implications of Shannon's theorems regarding joint source and channel coding for wireless communications are addressed. Following a brief introduction to speech, video and graphical source coding as well as the cellular concept, a rudimentary overview of flexible, reconfigurable mobile radio schemes is provided. We then summarise the fundamental concepts of modulation, introduce an adaptive modem scheme and argue that third-generation transceivers might become adaptively re-configurable under network control in order to meet backwards compatibility requirements with existing systems and to achieve best compromise amongst a range of conflicting system requirements in terms of communications quality, bandwidth requirements, complexity and power consumption, robustness against channel errors, etc.

Abstract

Commencing with the brief history of mobile communications and the portrayal of the basic concept of wireless multimedia communications, the implications of Shannon's theorems regarding joint source and channel coding for wireless communications are addressed. Following a brief introduction to speech, video and graphical source coding as well as the cellular concept, a rudimentary overview of flexible, reconfigurable mobile radio schemes is provided. We then summarise the fundamental concepts of modulation, introduce an adaptive modem scheme and argue that third-generation transceivers might become adaptively re-configurable under network control in order to meet backwards compatibility requirements with existing systems and to achieve best compromise amongst a range of conflicting system requirements in terms of communications quality, bandwidth requirements, complexity and power consumption, robustness against channel errors, etc.
