Abstract :
Constraints imposed on designing the decision feedback equalizers (DFE) are used effectively to mitigate propagation errors. In this paper, we introduce a novel design of the constrained minimum mean squared error (MMSE) DFE for a multi-input multi-output (MIMO) system under intersymbol interference (ISI) environment. The proposed design results in a significantly improved performance compared to the conventional MIMO MMSE-DFE, especially under the practical situation where the channel is not perfectly estimated and the channel coding is employed
