On the Achievable Degrees of Freedom of Two-Cell Multiuser MIMO Interference Networks

In this paper, we study the sum degrees of freedom (DoF) of an uplink two-cell multiuser MIMO interference network with asymmetric number of users in the cells. The achievable DoF is devised based on a two-dimensional space-time spreading code framework with linear precoding/decoding design and fini...
