摘　　要：The space-time spreading （SIS）, superimposed training sequences and space-time coding （STC） are adopted to obtain a closed-form of average error probability upper bound and maximum likelihood esti- mation expression for multiple input and multiple output （MIMO） correlated frequency-selective channel in the presence of interference （colored interference）. Moreover, the correlation at both ends of the wire- less link that can be incorporated equivalently into correlation at the transmit end is derived. Finally, the mean square error （MSE） of the maximum likelihood estimate is also derived.The space-time spreading(STS),superimposed training sequences and space-time coding(STC)are adopted to obtain a closed-form of average error probability upper bound and maximum likelihood esti-mation expression for multiple input and multiple output(MIMO)correlated frequency-selective channelin the presence of interference(colored interference).Moreover,the correlation at both ends of the wire-less link that can be incorporated equivalently into correlation at the transmit end is derived.Finally,themean square error(MSE)of the maximum likelihood estimate is also derived.
