Abstract
We propose a new structure of decision feedback adaptive equalizer (DFE) su itable for use in mobile radio systems. The proposed structure named Commut ating Decision Feedback Equalizer (CDFE) has two DFEs that operate in a com mutating fashion; the two DFEs commutate between training and equalization. Such a commutating operation effectively lengthens the equalizer tracking period over time variant channels. Thus, the CDFE has a superior performanc e over the conventional DFE in fading channels. Simulation results are pres ented in the paper.
