%X In this paper we have presented the effect of different modulation Techniques (QPSK, 16QAM and 64QAM) and number of antenna elements at the receiver (Smart Antenna) on the performance of beamforming in OFDM based Wireless network. The performance of the proposedtechnique is tested for adaptive beam forming algorithm, Least Mean Square (LMS), improved LMS and conventional beamforming for different number of antenna elements. Proposed system not only has goodability of suppressing interference, but also significantly improves the bit-error rate (BER)performance of the system. Simulation results show that an adaptive beam forming gives the optimum performance on urban channels. SNR vs. BER, are compared using same set of parameters.
