A mobile station including an input and a channel estimation module. The input is configured to receive a first signal from a first base station with which the mobile station is associated. The first signal has a first channel gain and is transmitted by the first base station using a plurality of pilot values. The input is configured to receive a second signal from a second base station with which the mobile station is not associated. The second signal has a second channel gain and is transmitted by the second base station using the plurality of pilot values. The channel estimation module is configured to generate, based on the plurality of pilot values, i) estimates of the first channel gain, and ii) estimates of the second channel gain.
