RFI Cancellation for an Array Radio Astronomy System With Receiver Nonlinearity

RFI Cancellation for an Array Radio Astronomy System With Receiver Nonlinearity

Radio frequency interference (RFI) is an important problem for a radio astronomy system (RAS) due to the very weak radio astronomical signals. Rapid expansions of active wireless systems (AWSs), as well as more demands for spectrum access by both AWS and RAS will result in scenarios with strong RFI....
