ABSTRACT:
A PN sequence signal estimator is described which synergistically co-operates with an adaptive array processor and a spread spectrum communication system modem such that the adaptive array will null interfering signals, but not desired signals. This is accomplished with the signal estimator generating an estimate of the desired coded signal through the use of the local code and the detected correlation in the modem, and feeding the estimate back to the array in such a manner that it subtracts from the array error voltage, thereby inhibiting null formation.
