> "Jamming attacks are common threats to wireless communications and happen when a hostile device creates radio signals that disrupt communications by decreasing the Signal-to-Inference-plus-Noise ratio (SINR)."
> "Possible ways that a software update can help bypass a jamming attack is if the jamming device is targeting a particular frequency. The software can implement FHSS or DSSS, Frequency Hopping / Spreading Sequences of frequencies for anti-jamming purposes. However, FHSS or DSSS, frequency distribution type of protection against jamming is flawed. It is ‘limited by a common assumption that the jammer can jam only part of the communication channels or has a limited transmit power.'"
That article points to this report, which discusses all kinds of novel ways to defeat such attacks, like using counter-jamming as a means of delivering bits between sender and receiver, bit synchronization schemes, and others:
