Coordinated Beamforming Technology in TD-LTE-Advanced System

Abstract

As extension of MIMO technology in cellular system with multiple cell sites, Cooperative Network MIMO is a hot topic for the research of future wireless communication. In current study of TD-LTE-Advanced (LTE-Advanced TDD) system, various coordinated beamforming schemes have shown to be very promising candidates. In this paper we introduce a few implementations of coordinated beamforming technology with different levels of coordination, together with system level simulations and analysis.
