Abstract
A receiver is provided for acquiring a DSSS signal. The receiver includes a splitter, a first multiplier, a second multiplier and a processor. The splitter is operable to split the DSSS signal into a first DSSS signal and a second DSSS signal. The first multiplier is operable to multiply the first DSSS signal by a shuffled pseudo-noise sequence and a sine function to obtain a first correlation value. The second multiplier is operable to multiply the second DSSS signal by the shuffled pseudo-noise sequence and a cosine function to obtain a second correlation value. The processor is operable to determine an alignment delay based on the first correlation value and the second correlation value.
