Abstract

In this paper, we propose the use of a combination of linear MMSE and soft successive interference cancellation based detectors for the application in (turbo-)MIMO receivers. In an adaptive setup we switch between the two detector types based on the quality of the received signal, while in a hybrid setup, we use a linear MMSE in the first and a SoftSIC in all subsequent iterations. We show that for a number of scenarios, both techniques show performance close to that of more sophisticated detection techniques, at a fraction of the complexity
