ABSTRACT:
According to a disclosed embodiment, a first plurality of pilot signals of a first polarization is received and ranked. Subsequently, a second plurality of pilot signals of a second polarization is received and ranked. Following, a pilot signal from the first and second pluralities of pilot signals is selected based on a signal quality measurement such as a signal to interference ratio. Moreover, a system can be constructed comprising antennas configured to receive pilot signals of a first and a second polarization. The system further comprises a receiver configured to demodulate the pilot signals and a CPU configured to rank the pilot signals and to select a pilot signal based on a signal quality measurement. Communication quality is improved by communicating with the base transceiver station transmitting the pilot signal providing the highest signal quality measurement.
