The problem of estimating second order statistics for MIMO channels is treated. It is assumed that the so called Kroneckermodel holds. This implies that the channel covariance is the Kronecker product of two covariance matrices associated with the transmit and receive array, respectively. The proposed estimator uses training data from a number of signal blocks to compute the estimate. This is in contrast to methods that assume that the channel realizations are directly available, or possible to… CONTINUE READING
