摘要
Anewmethodofestimatingthefrequency-knownsignalsfromthestrongbackgroundnoisewaspresentedfirst.Thenthenewmethodwasusedinthedemodulationofthedigitalfrequencymodulation(FSK)signals.ThenewdemodulationmethodcancompletethedemodulationoftheFSKsignalsonlywiththecarrierfrequencyandwithoutanycarrierphaseinformation.Thesimulationresultsshowthattheperformanceofanti-noiseofthenewmethodisbetterthanthatoftheincoherentdemodulationmethodandthefluctuationofthecarrierphasehaslittleeffectonthenewmethod.Sothenewdemodulationmethodhasafineprospectinthepracticalapplications.
