FDD Techniques Towards the Multimedia Era

Abstract

Global rendering of personalized multimedia services is the key issue determining the evolution of next-generation mobile networks. The determinant factor of mobile multimedia communications feasibility is the air-interface technology. The Universal Mobile Telecommunications System (UMTS) evolution, based on wideband code-division multiple access (WCDMA), constitutes a major step to the target of truly ubiquitous computing: computing anywhere, anytime, guaranteeing mobility and transparency. However, certain steps are still required in order to achieve the desired data rates, capacity, and quality of service (QoS) of different traffic classes inherent in multimedia services.
