Smart antenna is a current research focus. Basic principle of beam forming is introduced. The existing beam form?ing algorithms are classified and their performances are compared in accordance with the bind algorithm and non?blind algo?rithm. The adaptive beamforming algorithm based on wavelet transform and wavelet package is compared. Multi?resolution signal based on wavelet transform and beam forming algorithm based on wavelets neural network is analyzed. The prospect of the wave?let transform in optimal basis selection and the conjoint analysis with blind adaptive algorithm are looked forward.
