Patent ID: 8422381

Claim:
A system for improving jamming resistance comprising: a first node suitable for transmitting a coded preamble packet including a plurality of highly coded preambles, the first node further including: an encoder; and a modulator suitable for coding and modulating data transmissions sent from the first node, the first node transmitting the coded packet on a plurality of frequency channels by rapidly examining a plurality of available frequencies across the spectrum; and a second node suitable for receiving the coded preamble packet, the second node including: a demodulator; and a decoder programmed with at least one of the plurality of highly coded preambles utilized by the transmitting node, the second node matching a preamble code of one of the plurality of highly coded preambles and acquiring sufficient receiver timing to remove random transec code included in the coded preamble packet, the second node determining the relative strength of each channel utilized to transmit the coded preamble packet, selecting, via a probe, listen and select technique, a frequency band for transmitting a frequency channel response to the first node and transmitting a response to the first node, the response including new action frames providing transmission mode and channel information feedback including transmission mode feedback allowing the first node to inform a transmitting station of a selected channel mode for current channel conditions, the selected mode determined in real time by the first node based on frequency channel strength information in the channel information feedback, the channel information feedback providing a mechanism for the first node to learn a receiving channel seen at the second node.
