The frequency difference sensitivity of the modulation mode and the ability to overcome distortion by limiting amplitude of the signal and to overcome interference also affect the performance , too . in this paper , the relationship between the ability to overcome interference and the modulation mode is discussed at first . then the characters in some aspects specif ' ed above of some common modulation mode such as mfsk mpsk ofdm are studied . on this base , some according solutions to the problem of the different frequency - hopping system are put forward . in the past half of this paper , the realization scheme , pcrforemance and improving measures of ofdm are studied 本文首先較詳細(xì)地討論了跳頻抗干擾的能力與調(diào)制制度的關(guān)系,接著分別研究了幾種常用調(diào)制方式( mfsk , mpsk , ofdm )上述幾方面的性質(zhì),針對各跳頻系統(tǒng)存在的問題提出了相應(yīng)解決方案,在本論文后半部分重點討論了ofdm跳頻系統(tǒng)的實現(xiàn)方案、性能及改進措施。
