ABSTRACT:
A null processing receiver apparatus that receives and combines together a number of modulated information signals in such a fashion that an interference or jamming signal superimposed on each received signal is substantially eliminated from the combined signal. The apparatus first demodulates each received signal to baseband, to produce a primary demodulated signal and one or more auxiliary demodulated signals. The apparatus then appropriately weights the one or more auxiliary signals and sums together the weighted signals with the primary signal to produce a sum signal in which the interference is substantially nulled out. The weighting is based on a cross-correlation of the sum signal with the baseband signals themselves.
