Summary:
This paper proposes a new precoding scheme for multiuser massive MIMO systems. It is based on the previously proposed iterative approximation approach which exploits simple equal gain transmission (EGT) and inter-user interference (IUI) cancellation components. Although it offers low complexity by suspending iteration, IUI cancellation performance was limited. We derive its convergence solution to maximize IUI cancellation capability while maintaining complexity cost. Computer simulation verifies its effectiveness.
