A slow frequency-hopping (FH) spread-spectrum (SS) system with trellis-coded interleaved continuous phase modulation (CPM) is proposed, where the phase is continuous during each hop interval. The proposed system provides power- and bandwidth-efficient antijam capability in the presence of partial-band noise jamming. The proposed receivers use coherent or noncoherent iterative demodulation and decoding along with jammer state information. Furthermore, an iterative jamming state estimation technique is proposed to provide robust antijam performance.
