The performance of least mean square error（LMS） algorithm and normalized NLMS algorithm was researched in this paper.The factors that affecting beamformer were ananlysed and large amount of simulation was made to show their influence.The performance and convergence error of LMS and NLMS was campared and the simulation verified that NLMS was superior to LMS.
