Abstract
A wireless apparatus includes a first weight multiplication part, a channel estimation part, a channel response conversion part, and a second weight generation part. The first weight multiplication part includes first weights, each of which corresponds to an individual one of a plurality of beams, and multiplies a signal(s) corresponding to a reference signal(s) transmitted from a wireless terminal(s) by the first weights. The channel estimation part estimates first channel responses for the respective beams by using the signals obtained by the multiplication by the first weights. The channel response conversion part converts the first channel responses into second channel responses by using the first weights. The second weight generation part generates second weights used for wireless communication with the wireless terminal(s) by using the second channel responses.
