Abstract

We consider the application of multiuser detection to the downlink of interference-limited multiple-input multiple-output (MIMO) cellular systems. MIMO systems have been shown to yield a tremendous capacity for a single link with white Gaussian noise. In a cellular environment, there will often be co-channel interference from other cells, which becomes the dominating channel impairment. Here space-time layered architectures and turbo processing techniques are combined with multiuser detection techniques for combating intercell interference. Among various multiuser detection methods examined, linear MMSE and successive interference cancellation have been shown to be feasible and effective. Based on these two multiuser detection schemes, one of which may outperform the other for different settings, an adaptive detection scheme is developed.
