Title: Digital interference suppression system for radio frequency interference cancellation
Inventor: CASABONA MARIO M
IPC: H04B1/7097
Filed: 1998-06-23
Abstract: A digital signal processing system that produces an adaptive cancellation arrangement which nulls out all types of concurrent interference and/or jamming signals received by Global Positioning System (GPS) or spread spectrum receiver (7) from diverse antennas. In the present arrangement, orthogonal components of the composite received signal are separated by the receive antenna arrangement (3) and adjusted in the digital network (5) between the antenna (3) and the receiver (7) in phase and amplitude to optimally cancel components. The arrangements can be synergistically combined with digital adaptive transversal filter technology which is primarily used to supplement suppression performance by reducing narrowband interference in the band. The orthogonal received signal components from the GPS satellite constellation and from interference sources are combined in the present arrangement to adaptively create a null that attenuates interference sources while slightly modifying the GPS received signals.
