A system for synchronizing a DS-CDMA receiver (106) to a received signal (700) using actual data as opposed to a special training sequence is provided. A chip by chip multiplication (910, 1304) is appliced to a sequence of received chip complex values in order to eliminate most traces of bit sign information from the received signal (700). The foregoing allows multiple bit length sequences of chips extraced from actual data to be combined, e.g., averaged, in order to reduce random noise. A low noise vector which has been derived from actual data can then be used to synchronize (1312) the receiver (106) to a desired degree of precision. |
