—This article aims to provide a novel and efficient technique for pattern shaping and null steering in the environment of unwanted interferences. This paper presents a DSP based method, where at first DFT coefficients are obtained from spatial domain sampling and then operating by suitable window,function gives new set of DFT coefficients. IFFT(IDFT) over these coefficients provide complex weights which adaptively introduces null in the direction interference while keeping the main beam toward desired signal.
