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 for communication includes receiving modulated signals, which convey encoded speech. A measure of information entropy associated with the received signals is estimated. A speech encoding scheme is selected responsively to the estimated measure of the information entropy. A request to encode subsequent speech using the selected speech encoding scheme is sent to a transmitter.
