A Blind Equalizer for MIMO-OFDM Systems
Shan Ouyang · Journal of Guilin University of Electronic Technology · 2005
Abstrcat By making use of the vector reduced constellation algorithm (VRCA), the blind equalization of a wireless mobile communication system with multiple input multiple output and orthogonal frequency division multiplexing (MIMO-OFDM) is studied. The VRCA will minimize the cost function that is constructed by the difference between the equalized signal and the corresponding reduced constellation in four different quadrants. It wipes off the phase rotation off which the vector constant modulus algorithm cannot wipe.
