    摘要： An automatic gain control (AGC) method according to the present invention applies an initial gain by a digital AGC circuit (13) in a timeslot is determined using a final calculated gain from the same timeslot in the previous frame together with an offset factor. An erase function (14) is activated for a given data sample block when the number of saturated data samples that are detected within the block (17) exceeds a threshold value. The power measurement made by the AGC circuit and used to update the gain is adjusted based on the number of measured data samples that are saturated. These elements provide a gain limiting function and allows limiting of the dynamic range for further signal processing.

    摘要： A received power of a code division multiple access (CDMA) signal is determined. Samples of a spectrum associated with the received CDMA signal are taken as received samples (108), which are then correlated with a code of the CDMA signal (110). For correlated samples below a first threshold, those correlated samples are processed by being made to zero. For samples between the first threshold and a second threshold (114), those correlated samples are processed by rescaling (116). The correlated samples above the second threshold are passed unchanged. The received power level of the received CDMA signal is determined using the correlated samples after the processing.
