Linear constrained constant modulus algorithm (LC-CMA) is an effective solution to the problem of interference capture in constant modulus algorithm (CMA).But its performance is known to degrade substantially in the presence of even slight mismatches between the actual and presumed signal steering vectors.In this paper

we propose a novel approach to robust adaptive beamforming and analyze its performance.Our robust constrained constant modulus algorithm offers faster convergence rate

provides excellent robustness against the signal steering vector mismatches and improves array output SINR consistently.Computer simulations show better performance of our proposed robust adaptive beamforming algorithm than that of linear constrained constant modulus algorithm.
