| Abstract: | This paper studies mutual information transfer properties of iterative multiuser detector with linear precoding schemes for single carrier communications in multipoint-to-point multiple input multiple output (MIMO) channels. Based on multidimensional extrinsic information transfer (EXIT) analysis, we analyze the impact of linear precoding on the convergence properties of the detectors jointly designed with the precoders based on minimum sum mean squared error (MMSE) and maximum sum mutual information rate criteria. Results demonstrate that the use of the linear precoding schemes enhance the separability of the EXIT curves of the simultaneous streams over without precoding; This invokes the idea that different code rate be allocated to the each transmitted streams at the transmitters. |
