that apply. -High hopping rate of 76,923 hops per second
-Error Detection and Correction (EDAC) coding
-Pseudorandom frequency-hopping pattern over 51 discrete center frequencies
Which Link 16 jam resistance characteristic defines the power output needed to jam Link 16
communications at equal distances? Link margin
Which Link 16 jam resistance characteristic defines the required distance between a jammer
and a receiver to jam Link 16 communications using equal power? Range ratio
What technique is used by Link 16 terminals to correct errors and erasures in a message in
order to pass uncorrupted data to the host system? Reed Solomon Error Detection and
Correction (EDAC) coding
Which of the following IS NOT true of Link 16 spread spectrum processing? Decreases the
power transmitted over any single frequency
What are the three requirements for Link 16 direct connectivity? Select all that apply. -
Sufficient signal strength at the receiver
-Radio frequency (RF) Point-to-point line-or-sight (LOS)
