FIELD: radio engineering, communication.SUBSTANCE: invention relates to wireless communication. The wireless data transmission device is offered which comprises the data transmission module which transmits a reference signal, the first multiplication unit which performs multiplication by the first transmission weight determined on the basis of reception of reference signal by a partner during data exchange, and the second multiplication unit which performs multiplication by the second transmission weight determined on the basis of reception of reference signal by a partner during data exchange. The data transmission module transmits the reference signal with a weight obtained as a result of multiplication of reference signal by the first transmission weight after determination of the first transmission weight.EFFECT: decrease of the load connected with calculations on the partner during data exchange for determination of transmission weight is achieved.15 cl, 18 dwg |
