In this paper, an improved beampattern synthesis technique based on generalized sidelobe canceller (GSC) structure is proposed. Constrained optimization algorithm is used to control the beampattern from the main beam. Instead of selecting the blocking matrix in the noise subspace which is orthogonal to the signal-plus-interference subspace, we use the cyclostationary property of the transmitting signals...
In this paper, we propose an iterative algorithm, which can achieve beampattern control and adaptive beamforming at the same time. Our proposed algorithm is computationally efficient because it avoids the calculation of matrix inverse which is often required by conventional beampattern synthesis algorithms. Besides this advantage, the new algorithm is superior in being able to shape the sidelobe region...
