The performance of a direct sequence spread spectrum acquisition system employing a linear prediction filter

The authors analyze the performance of a direct sequence spread spectrum acquisition system employing a linear prediction filter to suppress a tone interferer located at the carrier frequency. They present a bound on the probability of error in the search mode and expressions for detection and false-alarm probabilities in the lock mode. They also give numerical evaluations of these expressions and compare them to analogous results on the the performance of an acquisition system employing a rectangular notch filter. It is shown that, when sinusoidal interference is present at the carrier frequency, a system employing a linear prediction filter can significantly outperform a system employing a rectangular notch filter
