Flexible spectrum use and better coexistence at the physical layer of future wireless systems via a multicarrier platform

Abstract

In this article we propose a new multicarrier platform to optimize the efficiency of wireless operators’ licensed hands and enable flexible sharing of licensed and unlicensed hands (in different spectral regions). This research, besides introducing a high degree of flexibility of spectrum use for 4G systems, supports a recent FCC proposal that goes beyond suggesting improved spectral efficiency, and instead suggests innovative spectrum management regulations. Specifically, this work presents a multicarrier platform capable of achieving high spectral efficiency by the application of narrow orthogonal carriers, that enables flexible spectral sharing across different licensed and unlicensed bands via operator borrowingilending.
