[Elecraft] RF Noise canceller ?

-----Original Message-----
Would this type of noise canceler not work on "white" noise also ?

White noise typically arrives from random directions, with random phases,
random polarizations, etc. etc. etc. and are usually from thermal and
uncorrelated sources.

<pick on details>
If you want to use the proper signal processing terminology here, then white
noise is a spectral property and only means broadband. It says nothing about
directionality. The corresponding directional term is isotropic noise.

So the answer is that the noise canceller works for noise sources with
directionality, white or not does not matter as our radios are narrowband
anyway. The assumption is that the noise is directional so that two antennas
can receive different proportions of signal and noise. The canceller will
not work with isotropic noise sources.
