摘要：
A system and method of training transmit or receive antenna array is disclosed. The method includes: a) entering an antenna training mode, b) receiving a training sequence to form a channel matrix (Q), c) constructing an updated receive beamforming vector (w) via a weighted averaging method, the weighted averaging comprising: w = ∑ i = 1 K a i q i , where qi is the ith column of the matrix Q, ai is the ith weighting coefficient, and K is the column size of the Q matrix, and d) sending another training sequence with the receive antenna array that has been beamformed with the updated w vector. The method further includes repeating b)-d) a plurality of times until the w vector is optimized. The method further includes beamforming the receive antenna array by the use of an optimized w vector.
