摘要: A channel response matrix is obtained by performing a training process between transmitter 401 and receiver 402 to obtain optimal signal phases of the antenna array. Next, singular-value decomposition (SVD) performed decompose into correlation eigenvalues. diagonal having square roots eigenvalues as its components obtained. all but one included in are replaced with zeros, setting amplitudes signals be applied array (antenna weight vector) for use wireless communication based on that reconstructed using component-replaced matrix. In this way, when implemented beam forming, time necessary find set direction can reduced.
