On achieving optimal degrees of freedom of MIMO cellular networks using decomposition
2013
2013 13th Canadian Workshop on Information Theory
This paper investigates the significance of decomposition-based schemes in achieving the optimal degrees of freedom (DoF) of multiple-input multiple-output (MIMO) cellular networks. We consider MIMO cellular networks with G cells, K users/cell with M antennas at each user, and N antennas at each base-station (BS). We assume all channels to be generic and time varying. We show that KM N KM +N DoF/cell can be achieved through one-sided decomposition of a MIMO cellular network (on the user side),
