In line-of-sight (LoS) channel environments, two data stream transmissions can be independently made by adopting dual-polarized antenna (DPA) system. The capacity of the DPA system is mainly affected by a rotation angle between the transmitter and receiver DPAs and channel gains of vertical and horizontal receiver antennas, which results in signal to interference and noise (SINR) ratio. In this paper, SINR is defined in the DPA system. Then, in order to improve the capacity of the DPA system, selection diversity is propsed. In the proposed scheme, the best DPA user in terms of SINR is selected based on both the rotation angle and the channel gains. The resultant capacity of the DPA system increases two times when the selection order is three. The selected best user can even achieve 3 times the capacity when the selection order is six. In addition to that, the average rotation angle of the selected user is also analyzed and provided.
