Abstract

According to a disclosed embodiment, a first plurality of pilot signals of a first polarization is received (304) and ranked (306). Subsequently, a second plurality of pilot signals of a second polarization is received (308) and ranked (310). Following, a pilot signal from the first and second plurality of pilot signals is selected based on a signal quality measurement (312) such as a signal to interference ratio. Moreover, a system can be constructed comprising antennas (124, 126) configured to receive pilot signals of a first and a second polarization. The system further comprises a receiver (120) configured to demodulate the pilot signals and a CPU (112) 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.
