Abstract :
Space-time (ST) coded eigenbeamforming (EBF) is studied in this paper. A group of eigenvectors of the spatial-correlated-matrix (SCM) are introduced as the weights of the ST code-matrix. In a multipath environment, EBF can channel the transmit power in the directions with the biggest gains. It works very well with downlink transmission and time-division-duplex modes. Since ST coded EBF technique combines diversity and beamforming techniques, it is one of the most important research directions in the realm of space-time coding.
