Abstract(s)

In a "Massive MIMO" context, we evaluate low-complexity iterative DF detection techniques involving interference cancellation at the output of an MF multiuser detector. These techniques can offer some performance advantage over the somewhat more complex (due to matrix inversion requirements) linear, ideal MMSE detection. Moreover, we can achieve close approximations to appropriate performance bounds - which are able to take into account channel estimation imperfections -, even for NR/NT <10, when NR/NT is also high enough to ensure iterative DF convergence.
