A wireless communication system includes a first communication device having an antenna arrangement configured to adjust the polarization of a radio frequency signal to be transmitted via the antenna arrangement, and a second communication device. A first downlink pilot signal having a first polarization and a second downlink pilot signal having a second polarization are sent via the antenna arrangement of the first communication device. The downlink pilot signals are orthogonal to each other and the polarizations are different. The downlink pilot signals are received at an antenna arrangement of the second communication device. A combined power of the received downlink pilot signals is optimized by varying a combining information. The combined power is a function of the received downlink pilot signals and the combining information. The antenna arrangement of the first communication device is adjusted based on the combining information.
