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
本文首先较详细地讨论了跳频抗干扰的能力与调制制度的关系，接着分别研究了几种常用调制方式( mfsk ， mpsk ， ofdm )上述几方面的性质，针对各跳频系统存在的问题提出了相应解决方案，在本论文后半部分重点讨论了ofdm跳频系统的实现方案、性能及改进措施。
