Abstract :
This paper aims to present a new approach for adaptive spatio-temporal DFE-based equalization applied to MIMO channels. The proposed MIMO-DFE is uses finite length feedforward and feedback matrix filters for the estimated channel. In addition the constraints of equal number channel inputs and outputs is removed and the receiver uses past and currently detected symbols to cancel the interference.
