Abstract
An adaptive signal processor, used for discriminating between a desired signal and several undesired signals, includes an arrangement of sensors, which samples the signals and forms a set of parallel electrical outputs each of which is proportional to a different linear combination of the desired and interfering signals, a set of complex weights, each of which multiplies a corresponding one of the electrical outputs thus forming a set of weighted signals, a coherent summing junction which coherently sums the weighted signals, thus producing a final output of the processor and a set of improved control loops which sample the parallel electrical outputs and the final output and generate from them a set of control signals to control the complex weights so as to drive them to optimal, steady states, and thereby to suppress the interfering signals and to preserve the desired signal at the final output of the processor. The control loops generate the control signals for the weights in such a way that the weights converge to their optimal steady states always in a fixed, predetermined and optimal amount of time which is independent of all parameters of the desired and interfering signals.
