    • A device for detecting data synchronization in data communications includes pseudorandom noise (PN) lock circuits (101, 113, 127). The PN lock circuits (101, 113, 127) receive an input data stream (109). Each of the PN lock circuits (101, 113, 127) is time offset with respect to the other PN lock circuits. Each of the PN lock circuits (101, 113, 127) outputs a PN sequence responsive to the input data stream. For each PN lock circuit, there is provided a component (105, 117, 131) for comparing the PN sequence from the respective PN lock circuit to the input data stream, to determine whether the input data stream and the PN sequence are synchronized. An indication (107, 119, 133) that the data is synchronized is provided when the input data stream and the PN sequence are synchronized.

    • 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.

    • A method is provided for adjusting timing alignment in which a receiver generates a plurality of imbalanced correction codes (1310), and square waves both having the same frequency. The receiver mixes the imbalanced correction codes with the square waves to create a mixed signal (1320), and integrates the mixed signal over a correction code period to generate a signal power value (1330). The receiver adjusts a phase of the square wave in a first direction when the signal power value satisfies a first criterion (1340, 1350), and in a second direction when the signal power value satisfies a second criterion (1340, 1360). Each imbalanced correction code is symmetrical. And a total integrated value of one of the imbalanced correction codes over the correction code period is either above a first threshold, or below a second threshold, the first threshold being greater than or equal to the second threshold.

The first code word format can be different in content and in size from the second code word format. By choosing different properties for each analog code word format, the device can optimize the performance of each operation.
