Abstract:

The model of correlated multiinput multioutput (MIMO) frequencyselective channels in frequency domain is introduced. And the pairwise error probability (PEP) of spacefrequency systems is analyzed based on this model. Then, the performance of spacefrequency equalizer (SFE) is derived and simulated based on minimum mean square error (MMSE). Analysis and simulation results show that the performance of spacefrequency systems degrades with the increasing of correlation.

Key words: frequency selective channels, channel correlation, spacefrequency equalization
