A transmit diversity system, method, and computer program product which can prevent signal power from being wasted and also prevent interference between a plurality of beams. In the transmit diversity system, a transmitter transmits a signal after allocating the signal to a beamspace of multiple beams and a receiver receives the multiple beams and obtains a channel estimate of each of the multiple beams. A beam pair, which has the largest sum of powers of respective channel estimates of two corresponding beams, is selected from a plurality of beam pairs of the multiple beams. One of the two beams of the selected beam pair is selected as a single beam for use if the difference between the powers of the respective channel estimates of the two beams is larger than a predetermined value.
