<p>A communication system environment estimation apparatus and method. In one embodiment, an environment estimation apparatus according to the teachings of the present invention includes a plurality of antenna elements and a receiver coupled to receive uplink signals from the plurality of antenna elements. The apparatus also includes a signal processor coupled to receive the uplink signals to select an estimation of an environment responsive to the uplink signals received from the plurality of antenna elements. A bit error rate (BER) in response the uplink signals received is measured and compared with an expected BER calculated from a measured signal to noise ratio. If the difference between the measured BER and the expected BER is greater than a BER threshold, a high interference environment is selected. <IMAGE></p> |
