Abstract
A method includes receiving a Code Division Multiple Access (CDMA) carrier carrying at least a pilot channel. Differences are computed between selected soft pilot symbols received on the pilot channel. Based on the computed differences between the selected soft pilot symbols received on the pilot channel, a level of noise is estimated for a data channel that is to be transmitted on the CDMA carrier.
