  • Publication number: 20020057729
    Abstract: An apparatus and method for locking onto a pseudo-noise code in an IS-95 spread spectrum communications system is disclosed. In response to an error signal, a pseudo-noise generator (312 or 416) generates an on-time pseudo-noise signal, an early pseudo-noise signal delayed by less than one-half of a chip interval, and a late pseudo-noise signal advanced by less than one-half of a chip interval. A correlator (302 and 304, or 404) correlates a received signal with the early and late pseudo-noise signals to generate the error signal. The combination of the pseudo-noise generator (312 or 416) and the correlator (302 and 304, or 404) creates a loop in which the on-time pseudo-noise signal tracks a received pseudo-noise code more closely than in prior art devices and enables a deinterleave and decode device (210) within the receiver to demodulate the received signal more effectively.
