Abstract
An apparatus and method of using spatial nulling in antenna electronics to protect against interference signals. Nulling is achieved by computing and adjusting the computed complex weights values of "n" channels through the use of dithering of interfering signals of having power levels thereby allowing nulling of "n" minus one number of interfering signal. sources.
