ABSTRACT:
An adaptive interference cancelling signal processing system includes N+1 processors for cancelling N interfering auxiliary signals from a primary signal. During a prelook or inactive period of the primary signal when a component of interest is not present in the primary signal, the N+1 processors are configured to produce the N(N+1)/2 correlation coefficients L.sub.ij which enable weights for the auxiliary signals to be determined. The same N+1 processors may be reconfigured to convert these L.sub.ij values to the N weights without requiring matrix inversion. The N+1 processors may be reconfigured to multiply the auxiliary signals by the N weights during an active period of the primary signal when the component of interest is present in the primary signal. These weighted auxiliary signals are combined with the primary signal to provide a modified primary signal from which correlated interference in the auxiliary signals has been cancelled.
