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 exible, reconfigurable, mobile radio schemes is provided. We then summarize the fundamental concepts of modulation, introduce an adaptive modem scheme, and argue that third-generation transceivers might become adaptively reconfigurable under network control in order to meet backward compatibility requirements with existing systems and to achieve best compromise among a range of con icting system requirements in terms of communications quality, bandwidth requirements, complexity and power consumption, robustness against channel errors, etc. Keywords— Cellular communications, channel coding, graphical source coding, modern transceiver, modulation, multimedia system schematic, multimode speech system, speech source coding, video-phone systems, video source coding, wireless channels, wireless communications, wireless multimedia communicator.
