Degrees of Freedom of MIMO <formula formulatype="inline"> <tex Notation="TeX">$X$</tex></formula> Networks: Spatial Scale Invariance and One-Sided Decomposability

We show that an M×N user MIMO X network with A antennas at each node has A(MN/(M+N-1)) degrees of freedom (DoF), thus resolving in this case a discrepancy between the spatial scale invariance conjecture (scaling the number of antennas at each node by a constant factor will scale the total DoF by the same factor) and a decomposability property of… (More)
