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.

Data channel noise estimation using pilot channel

A method includes receiving a Code-Division Multiple Access (CDMA) signal carrying at least a data channel, a pilot channel and a control channel. A first noise level is estimated on the pilot channel. A second noise level is estimated on the control channel. The first estimated noise level and the second estimated noise level are combined to produce a noise estimate of noise on the data channel.
