ANTENNAE DIVERSITY METHOD AND APPARATUS

摘要

An antennae diversity method and apparatus are applied in the Long-Term Evolution Advanced system including eight antennae. The method includes: setting up a space-time encoding matrix: S, wherein S1 and S2 are symbols before being encoded, the rows of the matrix stand for adjacent times or adjacent frequencies, the columns stand for weighting vectors, and the weight 1 and weight 2 are preset by the base station or generated adaptively; encoding with the encoding matrix to obtain the diversity processed symbols Y, wherein Y=W*S, W is the beamforming weighting matrix, W and W1 and W2 are the weighting vectors for the first and second beam respectively both with a dimension of 8×1.
