摘要：
A system includes a receiver, a processor and a decision device. The receiver receives a first signal via a first antenna, and one of the first signal and a second signal via a second antenna. The processor determines: based on the first signal as received at the first antenna, a first signal-to-noise ratio (SNR) and a first signal quality value; and based on the one of the first and second signals as received at the second antenna, a second SNR and a second signal quality value. The decision device selects one of the first and second antennas based on (i) a difference between the first SNR and the second SNR if the first SNR is greater than the second SNR, or (ii) the first signal quality value and the second signal quality value if the difference between the first SNR and the second SNR is less than a predetermined threshold.
