Anti-Jamming Performance of MFSK Signal Modeling and Analysis
摘要
Abstract
Aiming at the problem that analogue modulation method can’t meet the needs of military communication nowadays, this paper establishes a model of MFSK communication system and five jamming samples models (wide-band gauss noises, narrow-band noises, FM, tone). After discussing the characteristics of MFSK demodulation signal, this paper takes M=8 for example and analyzes the theoretical error rates under various jamming simples based on incoherent demodulation, then gives jamming effects of five jamming simples to MFSK signal by mathematic simulation. The simulation results show that among the interference effects in the same data rate, the multi-tone and FM occupy the first place, single-tone and narrow-band noises come secondly, and wide-band gauss is the worst, which provides valuable reference for the further study of jamming technology and effects in external field.关键词
