Abstract:
1. A method, comprising: in a communication terminal, receiving a Code-Division Multiple Access (CDMA) signal that was transmitted over a communication channel by a base station at a given transmission power and received at the communication terminal with noise of a given noise level, wherein the CDMA signal comprises at least a pilot channel that was spread using a pilot spreading sequence; de-spreading the received CDMA signal with the pilot spreading sequence, and calculating a pilot amplitude of the pilot channel based on the de-spread CDMA signal; and estimating, based on the received CDMA signal and the pilot amplitude, the transmission power of the base station and the noise level of the noise, by estimating one or more channel taps of a channel response of the communication channel, and normalizing the channel response by the pilot amplitude by dividing the channel taps by the pilot amplitude.
