Broadband Constraint Natural Gradient based Adaptive processing

Novel Broadband Constraint Adaptive Natural Gradient Array (BroCANA) Processing has been developed. The algorithm has been found capable of discriminating the desired signal among the broadband interference and noise sources. Mathematical analysis and MATLAB simulations confirm the suitability of algorithm for broadband applications. The technique has been further extended to the variable step size broadband array processing. A brief section on Wave number processing is also included.
