Effect of Modulation Schemes on Performance of OFDM Based Wireless Network Using Smart Antenna

This paper, the authors 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 proposed technique 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 good ability of suppressing interference, but also significantly improves the Bit-Error Rate (BER) performance of the system.
