Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: The present paper considers downlink eigen-beamforming for a multi-carrier CDMA mobile radio system. Three different versions of the spatial covariance matrix based on either short- or long-term averaging are investigated and their properties are assessed analytically and numerically.  highlight that, for environments with narrow angle spreads, the long-term spatial covariance matrix should be selected. In wide angle spreads, the short-term spatial covariance matrix, averaged over the whole system bandwidth, is an interesting trade-off beten the beamforming gain and the robustness to Doppler variations.
