Modular Precoding Based on Zero Forcing in Large Scale Antenna Systems with Imperfect Channel State Information
《Chinese Journal of Electronics》2017年第2期424-429,共6页XI Qi HE Chen JIANG Lingge 
supported by the National Nature Science Foundation of China(No.91438113,No.61371086);the National Technology Research and Development Program of China(863 Program)(No.2014AA01A704);the open research fund of National Mobile Communications Research Laboratory,Southeast University(No.2017D11)
In Large scale antenna systems(LSAS),the user number is usually much less than the number of base station antennas.By leveraging this characteristic,Modular precoding based on zero forcing(MZF) is proposed to achieve ...
