CIRCUIT AND METHOD FOR RAKE TRAINING DURING ACQUISITION

摘要

A method is provided for training a rake finger (200). In this method the rake finger receives a data signal including a plurality of signal components having a plurality of signal phase values, respectively. (620). The rake finger then sets a current acquisition phase for a locally-generated signal (620) and then calculates a value of an autocorrelation function for the received data signal with the locally-generated signal at the current acquisition phase. (630). The rake finger determines when the autocorrelation function is at a peak value (640), saving the peak value in a storage device (290) when the autocorrelation function is at the peak value (650). The rake finger can then set a finger weight (W) for the rake finger based on the peak value stored in the storage device. This method can be performed at least in part during an acquisition process for the rake finger.
