Procedures for analyzing interference caused by spread-spectrum signals

Abstract : A mathematical procedure is given for determining whether a spread-spectrum signal will cause an unacceptable interference condition in a victim receiver. The procedure involves calculating either the interference-to-noise ratio or the signal-to-interference ratio at the IF-amplifier output and comparing the ratio with an appropriate threshold value. The front end and IF amplifier of the victim receiver are treated as a bandpass filter and non linear processes are not considered. (Author)
