Radio frequency (rf) communications system having rf nodes that reacquire synchronization lock on frequency diverse, redundant data channels

A radio frequency (RF) communications system comprising:

• a first RF node configured to transmit redundant data channels on a plurality of respective different RF frequencies, each redundant data channel comprising
• a plurality of header blocks occurring at a first frequency, each header block having a synchronization field associated therewith, and
• an acquisition block occurring at a second frequency less than the first frequency;
• and
• a second RF node configured to
• receive the redundant data channels on the plurality of respective different RF frequencies and being subject to RF disruption so that a disrupted redundant data channel loses synchronization lock, and
• reacquire synchronization lock for the disrupted redundant data channel based upon data within another redundant data channel and in a shorter time than reacquiring synchronization lock using the acquisition block.

A method of radio frequency (RF) communications comprising:

• operating a first RF node to transmit redundant data channels on a plurality of respective different RF frequencies, and also to transmit a control channel for synchronization lock with at least one other RF node;
• and
• operating a second RF node to
• receive the redundant data channels on the plurality of respective different RF frequencies and being subject to RF disruption so that a disrupted redundant data channel loses synchronization lock, and
• reacquire synchronization lock for the disrupted redundant data channel based upon data within another redundant data channel and in a shorter time than reacquiring synchronization lock using the control channel.
