Degrees of Freedom of MIMO X Networks: Spatial Scale Invariance, One-Sided Decomposability and Linear Feasibility
Hua Sun, Chunhua Geng, Tiangao Gou +1
We show that an M X N user MIMO X network with A antennas at each node has AMN/(M+N-1) degrees of freedom (DoF), thus resolving in this case a discrepancy between the spatial scale…
Optimal Use of Current and Outdated Channel State Information - Degrees of Freedom of the MISO BC with Mixed CSIT
Tiangao Gou, Syed A. Jafar
We consider a multiple-input-single-output (MISO) broadcast channel with mixed channel state information at the transmitter (CSIT) that consists of imperfect current CSIT and perfe…
Subspace Alignment Chains and the Degrees of Freedom of the Three-User MIMO Interference Channel
Chenwei Wang, Tiangao Gou, Syed A. Jafar
We show that the 3 user M_T x M_R MIMO interference channel has d(M,N)=min(M/(2-1/k),N/(2+1/k)) degrees of freedom (DoF) normalized by time, frequency, and space dimensions, where…
Multiple Unicast Capacity of 2-Source 2-Sink Networks
Chenwei Wang, Tiangao Gou, Syed A. Jafar
We study the sum capacity of multiple unicasts in wired and wireless multihop networks. With 2 source nodes and 2 sink nodes, there are a total of 4 independent unicast sessions (m…
Aligned Interference Neutralization and the Degrees of Freedom of the 2x2x2 Interference Channel
Tiangao Gou, Syed A. Jafar, Sang-Woon Jeon +1
We show that the 2x2x2 interference channel, i.e., the multihop interference channel formed by concatenation of two 2-user interference channels achieves the min-cut outer bound va…
Aiming Perfectly in the Dark - Blind Interference Alignment through Staggered Antenna Switching
Chenwei Wang, Tiangao Gou, Syed A. Jafar
We propose a blind interference alignment scheme for the vector broadcast channel where the transmitter is equipped with M antennas and there are K receivers, each equipped with a…
