摘要
A new adaptive digital beamforming in receiving end based on compressed sensing is proposed. In the case of sparse array antenna, receiving signal from absence elements can be reconstructed by using the theory of compressed sensing. Adaptive digital beamforming techniques are then adopted to form antenna beams, whose main lobe is steered to desired direction and nulls are steered to the directions of interferences. Simulation results with Monte Carlo method show that the beam performances of the proposed method are approaching to that of full array antenna, and actual antenna elements can be reduced greatly.
