Abstract
A communication system includes an omnidirectional antenna to receive a wideband primary signal, a nulling antenna to receive a secondary signal and a controller. The nulling antenna is oriented to place a null in a direction of a desired communication signal and the controller subtracts a processed secondary signal from a processed wideband primary signal to produce a jamming cancelled signal.
Claims20
A communication system comprising:
- an omnidirectional antenna to receive a wideband primary signal;
- a nulling antenna oriented to place a null in a direction of a desired communication signal and to receive a secondary signal;
- a controller to subtract a processed secondary signal from a processed wideband primary signal to produce a jamming cancelled signal.
A method of communication comprising:
- receiving a wideband primary signal by an omnidirectional antenna;
- orienting a nulling antenna to place a null in a direction of a desired communication signal to receive a secondary signal;
- processing the secondary signal and the wideband primary signal;
- and
- subtracting a processed secondary signal from a processed wideband primary signal to produce a jamming cancelled signal.
