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

Abstract

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.
