Approximate capacity of the K-user fading MIMO MAC with common information
Henry P. Romero, Mahesh K. Varanasi · 2013
The capacity of the K-user fading multiple access channel with multiple antennas and common information is approximately characterized. In this model, any possible common message may exist. While the exact capacity appears to be difficult to characterize, it may be attained to within a gap independent of the power allocation by a simple separable coding scheme.
