N2 - A new adaptive beamforming scheme via NOncircularity-Rate Maximization (NORM) is presented for blind recovery of a narrowband signal with nonzero noncircularity degree (such as AM, ASK and BPSK signals). By maximizing the noncircularity rate of the output signal, this new second-order blind beamformer can directly extract the signal of interest from circular interferences and noise (both are not necessarily Gaussian) without training signal and array calibration. This NORM approach can be implemented in a completely closed form and is shown to be attractive than the customary high-order statistics (HOS) strategy for blind noncircular signal extraction in terms of computation burdens and output signal-to-interference plus noise ratio (SINR).
