Abstract

This paper examines the mutual interference that exists when broadband direct sequence spectrum signals and narrowband FM users are overlaid in the same frequency band. The paper also examines the ability of a novel adaptive tracking notch filter placed at the front end of the spread spectrum receiver to suppress strong cochannel narrowband FM users
