A TRANSMITTER WITH MULTIPLE TRANSMIT ANTENNAS USING POLARIZATION |
摘要 |
A transmitter for transmitting data in a cellular radio system is provided. The transmitter transmits data to User Equipment(s) using multiple transmitting antennas, using at least two polarization formers generating orthogonal polarizations of an input data stream. The transmitter further comprises a transmitter diversity arrangement adapted to receive input data to be transmitted to the User Equipment(s), where the transmitter diversity arrangement is connected to the input terminals of the polarization formers. By combining transmitter diversity with polarization former weights, orthogonality between multiple, in particular 4, transmitting antennas can be obtained. |
