A time-domain fingerprint for BOC(m, n) signals

Binary offset carrier ( BOC) describes a class of spread-spectrum modulations recently introduced for the next generation of global navigation satellite systems ( GNSSs). The design strategies of these BOC signals have so far focused on the spectral properties of these signals. In this paper, we present a time-domain fingerprint for each BOC signal given by a unique histogram of counted time elapses between phase jumps in the signal. This feature can be used for classification and identification of BOC-modulated signals with unknown parameters. Copyright (c) 2007 B. Muth et al.
