Research abstract
IN THIS PROPOSAL, COHERENT ADAPTIVE FILTERING INVOLVES INJECTING TIME DELAYED OR PHASE ADJUSTED WEIGHTED SAMPLES OF A REFERENCE INPUT INTO A SIGNAL LINE SUCH THAT THE MEAN SQUARE (MSE) OF THE SIGNALS IN THE LINE IS MINIMIZED. THIS YIELDS NULLING OF SIGNALS COHERENT WITH THE REFERENCE. THE CONVERGENCE ALGORITHM FOR ADAPTATION OF THE WEIGHTS WHICH MAKES THIS APPROACH TECHNICALLY AND ECONOMICALLY PRACTICAL FOR A STEERABLE ARRAY, FREQUENCY-AGILE RADIO IS A MODIFIED LEAST MEAN SQUARE (LMS) ALGORITHM.
