Abstract
An antenna system may include an antenna array configured to receive one or more signals. In embodiments, the antenna system further includes one or more signal processors configured to: determine a beamforming weight vector (Wbf) for the antenna array; determine a first seeding weight vector (Wseed1) for the antenna array, wherein the first seeding weight vector (Wseed1) comprises a first nulling weight vector (Wnul1) or a second beamforming weight vector (Wbf); determine a first nullforming adjustment factor (η1) for the antenna array; calculate a first nullforming weight vector (Wnf1) based on at least the beamforming weight vector (Wbf), the first seeding weight vector (Wseed1) and the first nullforming adjustment factor (η1); and form a first antenna pattern based on the first nullforming weight vector (Wnf1) to generate a first antenna electronics (AE) output signal, wherein the first antenna pattern generates a first set of one or more nulls.
