a system for processing modulated signals received , together with at least one interference signal , by an array of antenna elements in a communications receiver . the method of the invention includes demodulating the received signals , and processing the demodulated signals to produce an output signal that is substantially free of any interference signals , while at the same time effectively steering the antenna pattern produced by the array of elements , to move any spurious nulls in the pattern away from a source of information signals . this results in avoidance of any cycle slipping problems that might otherwise arise in receiver tracking control loops , and has the added benefit of significantly improving performance as measured by the signal - to - noise ratio .
