FSK 변조에 의한 CPM DS-SS 통신시스템의 단일주파수 잡음에 대한 성능평가

Performance Analysis aginst Single Tone Jamming for CPM DS-SS System with FSK Modulation.

This paper has analyzed the performance against a single tone jamming for the CPM DS-SS system with a Binary FSK Modulation. The CPM DS-SS system designed with the different phase shift of the same pseude-noise code has the advantage of reducing the jamming and interference effects on multi-users communication environment. Analytical results show that the system preformance improves by increasing parrallel users in the presence of the coherent single-tone, which is the worst interference since the jamming signal has the same frequency as a carrier.
