Space-Frequency Equalization in Correlated MIMO Frequency-Selective Channels
Dacheng Yang · Beijing Youdian Xueyuan xuebao · 2007
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.
