Jamming Rejection
–
Active Interference Cancellation
Jamming Rejection can be used for solving narrow band (CW) EMI problems in the
customer’s system. It is effective against narrow band clock harmonics. Jamming
Rejection is not effective against wide band noise, e.g. from a host CPU memory bus or
switching power supply because these sources typically cannot be distinguished from
thermal noise. A wide band jamming signal effectively increases the noise floor and
reduces GNSS signal levels.
Please refer to section 4.9 Jamming Rejection
Active Interference Cancellation (AIC) for
further details.
