Weblarly, in [16], compressive demodulation of direct sequence spread spectrum (DSSS) with offset quadrature phase shift keying (OQPSK) is considered. Among related work from the literature, that described in [17] is closest to that proposed here. Speciﬁcally, data bits are directly detected from com-pressive measurements of FHSS-GFSK signals.
