Research and demonstration on beyond 3G systems

In this contribution, some important issues toward B3G (beyond 3G) mobile communication systems are analyzed, including the developing tendency, promising technologies, and demonstration system construction. Advanced technologies for B3G application are introduced comprehensively from physical layer techniques to network layer strategies. The B3G demonstration system developed in WTI (wireless technology innovation) lab is termed as TD-MC-CDMA system. Technical scheme and simulation results of TD-MC-CDMA demonstration system are presented. Discussions for the prediction of next generation mobile communication systems are given.
