[0023] According to the present invention, in the same MIMO system, when transmitting data to different mobile terminals, the base station selects a reasonable transmission antenna polarization mode and spatial coding mode according to the different wireless receiving environments where the corresponding mobile terminals are located, so that the It is beneficial for the mobile terminal to obtain better reception performance, so as to improve the overall performance of the wireless system.
[0024] figure 1 A wireless communication system composed of a MIMO-based base station and a plurality of mobile terminals under its jurisdiction is shown according to a specific embodiment of the present invention. The illustrated base station 10 includes a plurality of transmit antennas 31 . . . 3n, and these transmit antennas can support a variety of different transmit antenna polarizations, including but not limited to cross-polarization and vertical polarization. According to the pres...
