A Novel Robust Cyclostationary Beamformer Based On Conjugate Gradient Algorithm

Based on conjugate gradient (CG) algorithm, the authors propose a novel robust cyclostationary beamformer algorithm, which can be used to extract signals with cyclostationarity in the presence of cycle frequency error (CFE). Compared to conventional cyclostationary beamforming algorithm, the proposed approach doesn't need to estimate the actual cycle frequency, and can get higher output signal-to- interference plus noise ratio (SINR)
