Performance of adaptive modulation assisted adaptive beamforming system

Due to limited spectrum and increasing demand for wireless application, efficient use of wireless channel is becoming more important. In this paper, we propose a new approach of adaptive modulation to be employed in adaptive beamforming system to increase spectral efficiency while maintaining transmission quality. With a guarantee of bit error rate (BER) =10-2 and 10-4, our proposed method can achieve average throughput of 4bits/symbol at signal-to-noise ratio (SNR) = 16dB and 22dB, respectively.
