Capacity Regions and Sum-Rate Capacities of Vector Gaussian Interference Channels
arXiv:0907.0472 · doi:10.1109/TIT.2010.2059950
Abstract
The capacity regions of vector, or multiple-input multiple-output, Gaussian interference channels are established for very strong interference and aligned strong interference. Furthermore, the sum-rate capacities are established for Z interference, noisy interference, and mixed (aligned weak/intermediate and aligned strong) interference. These results generalize known results for scalar Gaussian interference channels.
