The main component used in the present day cellular network is an adaptive smart antenna, which with the help of a cell site transmit signal in a specific direction reduces undesired interference. In this paper, a sign leaky least mean square (SLLMS) algorithm and normalized leaky least mean square (NLLMS) algorithm is introduced for beam forming in smart antenna. A comparative study is done based on ability to generate main beam towards desire user, to generate null toward interferer, maximum side lobe level (SLLmax) and convergence by varying the signal-to-noise ratio (SNR).
