Recently, the next generation (5G) mobile communication system has been actively investigated all over the world, in order to satisfy the strong demand for the faster and larger data communication. not only UHF band but also SHF/EHF bands have been much attracted much attention. Therefore, frequency characteristic of radio propagation loss must be studied. We previously investigated the outdoor to...
Multiuser MIMO (MU-MIMO) improves the system channel capacity by employing the transmission between a base station (BS) and multiple user terminals (UTs). Block Diagonalization (BD) has been proposed as a practical algorithm in MU-MIMO broadcast channel. However, when the number of transmit antennas is equals to the total number of received antennas, the transmission rate by the BD algorithm is decreased...
