Claim:
1. A receiver system for receiving user signals from a plurality K of signal sources distributed in an area of coverage transmitting signals in a multiple access mode in a presence of a plurality N J of jammers comprised of jammers in the area of coverage wherein N J is an integer greater than or equal to 1, the system comprised of: an array of multiplicity N antenna feeds for receiving radio frequency (RF) signals from the plurality K of user signal transmission sources; an RF to baseband conversion subsystem inputted with the RF signals from the array of antenna feeds for RF to baseband conversion of the RF signals for providing a multiplicity N of complex baseband signals; a multiplicity M of digital beamformers, wherein M is an integer greater than 1, inputted with the multiplicity N complex baseband signals, each of the plurality of digital beamformers providing a respective one of a multiplicity M beamformer outputs with the digital beamformer m for m equal to 1 through M comprised of a corresponding distinct adaptive algorithm selected from a group comprised of a multiplicity N a channelizer subsystem comprised of a multiplicity M channelizers wherein a channelizer m for m equal to 1 through M is inputted with the output of the respective digital beamformer m of the multiplicity M digital beamformers for providing a multiplicity K of distinct constituent user complex baseband signals comprised of a constituent user k complex baseband signal for k equal to 1 through K by a separation operation performed on the output of the digital beamformer m of the multiplicity M of digital beamformers; a multiplicity K of weighted combiners wherein a weighted combiner k for k equal to 1 through K of the multiplicity K of weighted combiners combines the weighted respective multiplicity M constituent user k complex baseband signals outputted from the multiplicity M of channelizers for providing a corresponding reduced interference user complex baseband signals k for k equal to 1 through K of the multiplicity K of reduced interference mitigated user complex baseband signals.
