Abstract :
Two delay estimators that mitigate the effects of a tone jammer are presented. They are based on the phase interference extractor (PIE) and auxiliary-vector (AV) data detection principles. The estimators are analyzed by computer simulations and shown to tolerate more powerful jammers than the conventional correlator estimator does
