Description
Summary:Beamforming (BF) transmission for broadband massive MIMO systems in frequency-selective Ricean fading environments is investigated. By treating the scattered component as interference in order to reduce the heavy overhead for estimating channel state information, a transmit/receive BF scheme only based on the specular component is presented. It is shown by analytical results that the ergodic achievable rate for the scenario with doublyended spatial correlation can be asymptotically equal to that of the one without correlation when the transmit power is scaled down by the multiplication of the two numbers of antennas at the transmitter and the receiver. It is also shown by simulation results that different from the traditional point of view, spatial correlation can improve the rate performance of the proposed BF scheme.
