Minimum variance distortionless response beamformer with enhanced nulling level control via dynamic mutated artificial immune system

In smart antenna applications, the adaptive beamforming technique is used to cancel interfering signals (placing nulls) and produce or steer a strong beam toward the target signal according to the calculated weight vectors. Minimum variance distortionless response (MVDR) beamforming is capable of de...
