Jamming mitigation based on coded message-driven frequency hopping

This paper proposes an anti-jamming system based on coded message-driven frequency hopping. In each hopping period, multiple frequency bands are utilized for signal transmission. The selection of these bands is determined by a coded message sequence, hence the proposed scheme ¿hops¿ its frequencies randomly without a pre-defined pseudo-random sequence. Error correction codes are employed in an innovative way for accurate hopping pattern retrieving, and can also be exploited for jamming detection. The proposed scheme achieves strong jamming resistance while maintaining high spectral efficiency.
