Abstract

This paper computes the probabilities of detection and false alarm for a pseudonoise (PN) sequence code lock detector when a strong radio frequency interference (RFI) hits the communications link. A soft-limiter, a hard-limiter, and no limiter at the front-end of the receiver are considered. Both continuous wave (CW) type RFI and pulse type RFI are analyzed. It is shown that a soft-limiter or a hard-limiter can protect the PN-code lock detector against a typical pulse RFI, but in a CW RFI environment, the PN-code lock detector performance with a soft-limiter or a hard-limiter will be worse than that with no limiter
