An estimator of the spatial correlation coefficient for frequency selective time invariant MIMO channels is proposed. Numerical results show that the proposed SCC estimator performs better than the widely used classic SCC estimator. Based on numerical simulations, the trade‐off between the maximum tolerable mean‐squared error of the proposed SCC estimator and the measurement bandwidth is shown.
