Abstract : The patent relates to an improved system and technique for reducing interference in signal receiving systems, particularly in sidelobe canceller systems. Adaptive canceller loops receive inputs from an auxiliary channel signal and operate on a main channel signal to reduce interference in the main channel signal. The auxiliary channel signal is supplied through a quadrature hybrid circuit to provide I and Q components to the adaptive loops, which loops are connected in series and cascaded such as to form a plurality of serially connected I and Q loops.
