User partitioning for less overhead in MIMO interference channels
IEEE Transactions on Wireless Communications, 11(2), 592–603.
Contributors: S. Peters* & R. Heath Jr.
author keywords: MIMO; multiaccess communication; interference alignment; ad hoc networks; multiple access interference
TL;DR:
Simulations show that the proposed greedy methods switch from time-division to interference alignment as the coherence time of the channel increases, and have a small loss relative to optimal partitioning only at moderate coherence times.

Transmission capacity of Ad-hoc networks with multiple antennas using transmit stream adaptation and interference cancellation

author keywords: Ad hoc network; beamforming; multiple antennas; interference cancelation; spatial multiplexing; transmission capacity
TL;DR:
Using the obtained bounds, the optimal number of data streams to transmit, and the optimal SRDOF to use for interference cancellation are derived that provide the best scaling of the transmission capacity with the number of antennas.

Spatial interference cancellation for multiantenna mobile ad hoc networks
IEEE Transactions on Information Theory, 58(3), 1660–1676.

author keywords: Ad hoc networks; adaptive arrays; channel estimation; interference cancellation; multiple-input multiple-output (MIMO); Rayleigh channels
TL;DR:
Numerical results suggest that canceling merely one interferer by each node may increase the transmission capacity by an order of magnitude or more, even when the CSI is imperfect.
