Abstract:
A wireless transmitting method includes calculating a beamforming channel matrix which is a channel matrix generated at a time when a transmitting apparatus applies a beamforming matrix to a data signal and transmits the data signal to receiving apparatuses, selecting a parameter to be used while transmitting the data signal based on the beamforming channel matrix and noise information fed back from the receiving apparatuses, and transmitting the data signal by using the selected parameter.
