Abstract

This paper studies efficient structure of multiband mobile communication system which can support both high data rate services and wide coverage. First, we show design criterion of appropriate bandwidths in multiple frequencies. Second, we show a realistic scenario of smooth migration from singleband system to multiband system, considering investment risk and frequency license problem. Third, we study multiband MC-CDM system for downlink, that is a multiband system combined with MC-CDM system. The presented multiband MC-CDM system includes efficient structures of pilot signals, two dimensional spreading, and simplified receiver.
