<p>A transmitter reduces a burden on a process for determining allocation of a weight vector to each of receivers in multiplex transmission of signals to be transmitted to a plurality of receivers using a plurality of antennas. A transmitter (10) multiplexes signals to be transmitted to receivers (20, 30, 40) according to a weight vector, and transmits multiplexed signals wirelessly using antennas (11a, 11b, 11c). A control section (12) for the transmitter (10) at first selects a first receiver for allocation of a weight vector. Sequentially, the control section (12) outputs to a second receiver the information on a candidate for a weight vector enabled in parallel with a weight vector allocated to the first receiver, and then allocates a weight vector to the second receiver in accordance with the feedback information from the second receiver.</p> |
