Polarized MIMO Transmission Using Relay in Urban Area

In a polarized MIMO transmission, performances of the system deteriorates due to the difference between the transmission characteristics of horizontal polarization and vertical polarization. In this paper, we will examine the influence of a relay station position on channel capacity for relay transmission in polarized MIMO. As a result, it is clarified that a high channel capacity is stably obtained when the relay station and the reception point is in the line-of-sight environment.
