A computationally-efficient FIR MMSE-DFE for multi-user communications

A new theoretical framework is introduced for analyzing the performance of a finite-length minimum-mean-square-error decision feedback equalizer (MMSE-DFE) in a multi-input multi-output (MIMO) environment. The framework includes transmit and receive diversity systems as special cases and quantifies the diversity performance improvement as a function of the number of transmit/receive antennas and equalizer taps. Closed-form expressions for computing the finite-length MIMO MMSE-DFE are presented for two common multi-user detection scenarios.
