Abstract

In response to an error signal, a pseudo-noise generator ( or ) 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 ( and , or ) correlates a received signal with the early and late pseudo-noise signals to generate the error signal. The combination of the pseudo-noise generator ( or ) and the correlator ( and , or ) 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 ( ) within the receiver to demodulate the received signal more effectively.
