Capacity Regions and Sum-Rate Capacities of Vector Gaussian Interference Channels

摘要

The capacity regions of vector, or multiple-input multiple-output, Gaussianinterference channels are established for very strong interference and alignedstrong interference. Furthermore, the sum-rate capacities are established for Zinterference, noisy interference, and mixed (aligned weak/intermediate andaligned strong) interference. These results generalize known results for scalarGaussian interference channels.
