Abstract :
Time and frequency transfer techniques that rely on spread spectrum group-delay measurements are prone to potentially large timing errors caused by coherent interference that is time delayed. Reducing the level of the coherent interference, increasing the pseudo-random code rate, or using a fractional correlator can minimize these timing errors
