- W2390203944 abstract "In the paper,a MIMO(multiple-input multiple-output) precoding matrix construction method based on Schimidt orthogonalization is proposed,which uses the initial codebook generated by Grassmannian space packing principle.According to the CSI(channel state information),the receiver chooses a precoding vector from the Grassmannian initial codebook,which can match the CSI best by the criterion of the minimum bit error rate,then feedback the codebook index of the chosen precoding vector to the transmitter through the feedback link.Then the base station finds out a most similar vector with the feedback one in the Grassmannian codebook according to the number of the layer mapping.At last,we construct the resultant precoding matrix by Schmidt orthogonalization.Simulation results show that the proposed method has better BER performance than that based on the Householder transform in 3GPP LTE R8,and it is also easy to be realized with better flexibility." @default.
