摘要

研究表明，相关过程对窄带干扰的抑制与调制序列长度有关，而与调制类型关系不大。调制类型决定了I/ q分量的形状及其频谱形式。因此，基于最弱的窄带干扰抑制，对BOC(n)和MSK-BOC(n)类型进行了比较分析。当调制序列长度相同时，MSK-BOC的抗扰度比BOC高2 dB以上。

Comparative analysis of narrow band interference immunity for BOC and MSK-BOC receivers

Paper shows, that narrow band interference suppression given by correlation process is dependent on modulating sequence length and less on modulation type. Modulation type determines shape of I/Q-components and its spectrum form. Thus the comparative analysis for BOC(n) and MSK-BOC(n) types is given relying on the weakest narrow band interference suppression. When the modulating sequence length is the same, MSK-BOC's immunity is more than 2 dB better than BOC's.
